When we finish our training, we often forget a lot of what we went through in the program. For example, not everyone remembers how many milligrams are in a gram. However, this knowledge is sometimes simply necessary in everyday life. For example, the correct dosage of various components in cooking, medicine, and cosmetology often depends on how well we have mastered the system for converting weight from kilograms to grams, from grams to milligrams. If you take this lightly, you can easily ruin the result. After all, it is much easier to figure out how much to add and where, knowing how many milligrams are in a gram. Small values ​​are often used when working with small volumes of substances, and it is very important not to confuse the ratio. Even on the Internet, you can sometimes come across statements that confidently say that a gram contains 100 milligrams. But it is quite possible that, after reading such a post, another person will simply make a mistake with his calculations. So, how many milligrams are in a gram? And how to do the calculations correctly?

A milligram is a thousandth of a gram. The value of the prefix "milli" means 10 to the -3 power, respectively, indicating one thousandth. That is, one gram consists of one thousand milligrams. In fact, it is not at all difficult to convert these values ​​even without a calculator. To do this, it is enough to use the most basic knowledge of arithmetic.

To make it easier to understand how many milligrams are in 1 gram, I will present a clear example:

1 gram is equal to 1,000 milligrams

And vice versa:

1 milligram is equal to 0.001 grams

It follows that:

1 kilogram is equal to 1,000 grams, which is equal to 1,000,000 milligrams

Using such a simple table, you can correctly calculate the amount of substances.

Knowing how many milligrams are in one gram is necessary if you want to correctly follow recipes for various cosmetics and medications. After all, situations often arise when we can independently understand all the subtleties and nuances, but ignorance of how many milligrams are in a gram and well-founded uncertainty about the correctness of the calculations prevents us from finding a rational solution.

Let's say you need to give medicine to a small child. But it is known that the dosage of some drugs differs quite strictly between adults and children. In this case, the most difficult thing is to choose the required dose that will not cause any side effects or negative health effects for very young children, up to three years old. Having a whole tablet and knowing its standard weight, as well as the amount of active substance, you can easily do this. In an example it looks like this.

Tablet weight is 500 milligrams. The pediatric dose of this drug is 0.25 grams. Difficult? Not at all. One has only to use the elementary school formula and everything will fall into place. You can use two different ways to convert values ​​- from grams to milligrams or vice versa. This is what the result will be:

500 milligrams = 0.5 grams. And you only need 0.25. We divide the tablet into two parts and get the required dose of the required medicine.

You can do the other way around:

0.25 grams = 250 milligrams

The result is two numbers - 500 milligrams and 250 milligrams. And now it is much easier to understand how to properly split the tablet.

I will give a few more examples of converting grams to milligrams and vice versa.

0.12 grams = 120 milligrams.

540 milligrams = 0.54 grams

0.03 grams = 30 milligrams

36 milligrams = 0.036 grams

Here's how you can easily deal with such incomprehensible quantities. There is no need to divide or multiply if you correctly understand the number of zeros. In the version with 540 milligrams, 0.54 grams can be obtained by simply moving the separating comma three digits forward, which means three zeros in 1000. After all, did you remember that there are 1000 milligrams in one gram? And in the case of converting 0.03 grams to milligrams, the comma is moved back three digits and the missing zero is added. 0.030 = 30.

1000 mg - how many grams is it?

1000 milligrams, in fact, this is not a lot, and one can even say little, since in total, this menacing-looking figure is nothing more in its total equivalent than one gram (1 gram) weight, this or that substance.

Chemistry is a very exact science, I remember in practical classes at school we constantly weighed these same milligrams and grams. What if you make a mistake, you can screw up such things, even an experienced teacher will not be able to help.

With age, everything is done by eye.

One milligram seems very little, because the prefix milli is a reduction of 1000 units. So 1000 mg is 1 gram.

10000 mg is 10 grams

This is called jewelry precision, because when a ring is cast, they always monitor the weight of the finished product. A gram of product is very expensive, and an additional milligram can significantly increase the cost of the finished product.

So when buying, how much should you weigh in gram or milligram?)

Mille is a thousand in Latin.

In the international system of SI units, it was agreed that what is a thousand times smaller than the base unit (gram, in our case) is written with the prefix milli- (and what is 1000 times more is written with the prefix kilo-, also a thousand, but narrower from Greek).

A millimeter is one thousandth of a meter, for example.

A milligram is one thousandth of a gram.

1000 * (1/1000) = 1 (One) gram.




1000 mg = 1 gram, 1000mg: 1000 = 1 gram

Millie is a prefix used to express the thousandth part of something, in our case a gram.

Milli is a unit of measurement, denoted in Russian by the letter m and international m, used in the International System of Units (SI).

A million is a thousand thousand or 1000000: 1000 = 1000 we check and get 1000*1000 =1000000.

1000ml: 1000 = 1l. (liter).

1000mm: 1000 = 1m. (meter).

As you can see from the examples, milli is mainly used to reduce numbers by 1000 so that the numbers can be written and symbolized without adding zeros, which actually makes working with numbers easier.

In the worldwide accepted system of units of measurement, there are multiple (for example, kilogram) and submultiple (for example, gram) units. So, a milligram is also a submultiple unit equal to 10 minus 3 powers of gram or gram/1000, which is expressed as 0.001 grams. Accordingly, if 1000 is multiplied by 0.001, we get 1 gram.

When we need to weigh something very small and very light, we need very accurate scales. They are very delicate (you cannot weigh heavy things on them) and the weight in them is calculated not in tons and kilograms, but in grams and milligrams.




1 mg is equal to 0.001 g, therefore 1000 mg is 1 g.

This measure of scales has found application in pharmacy and jewelry.

Don’t think that 1000 mg is very little, since everything is relative.

For example

if one tablet of some expensive medicine weighs 20 mg, then 50 such tablets will be exactly our weight, and if we take into account that a plate of such tablets (10 pieces) will not be cheap, then five such tablets will cost a tidy sum.

Oh, these weights and lengths, units of time... all these grams and milligrams, it’s not so easy to remember them all and convert one into another! From school, I remember the back page of a checkered notebook - there was always a hint with which you could convert meters into millimeters, grams into kilograms.

So, let's look at what 1000 mg is, that is, one thousand milligrams. The prefix milli in the word milligram indicates that 1 gram is 1000 times larger than 1 milligram. And this means that 1 gram = 1000 milligrams.

The same can be said about millimeters: a meter is 1000 times larger than a millimeter, which means there are 1000 millimeters in 1 meter.

The prefix milli is the answer to your question. It reduces the number by a thousand units, so 10,000 milligrams is 10 grams, and, accordingly, 1,000 milligrams is just one gram.

A smaller unit of measurement is micrograms.




One thousand milligrams is exactly one gram of weight (or mass). This is written in numbers like this: 1000 mg = 1 g. And one milligram is exactly one thousandth of a gram. Or 0.001 g x 1000 = 1 g.

Milli- is a prefix to a unit of measurement, denoting one thousandth of a given unit. So if I have no idea what, say, the sievert unit is, I know for sure that the sievert includes 1000 millisieverts. Can be applied to any unit that does not contain other similar prefixes. So, a millihour is equal to 3.6 seconds. At one time, students proposed a unit for measuring talkativeness - Ken. Their physics teacher (Millikan) had the eponymous loquacity. The idea of ​​prefixes to units of measurement was very deeply felt by the monkey, who said: Your height is equal to two halves of you, or four halves of a half. I recommend thinking about the topic - why is it that the circumference of the Earth is exactly 40 thousand kilometers.

More about mass

General information

Mass is the property of physical bodies to resist acceleration. Mass, unlike weight, does not change depending on the environment and does not depend on the gravitational force of the planet on which this body is located. Mass m determined using Newton's second law, according to the formula: F = ma, Where F- this is strength, and a- acceleration.

Mass and weight

The word “weight” is often used in everyday life when people talk about mass. In physics, weight, in contrast to mass, is a force acting on a body due to the attraction between bodies and planets. Weight can also be calculated using Newton's second law: P= mg, Where m is the mass, and g- acceleration of gravity. This acceleration occurs due to the gravitational force of the planet near which the body is located, and its magnitude also depends on this force. The acceleration of free fall on Earth is 9.80665 meters per second, and on the Moon it is approximately six times less - 1.63 meters per second. Thus, a body weighing one kilogram weighs 9.8 newtons on Earth and 1.63 newtons on the Moon.

Gravitational mass

Gravitational mass shows what gravitational force acts on a body (passive mass) and what gravitational force the body acts on other bodies (active mass). When increasing active gravitational mass body, its force of attraction also increases. It is this force that controls the movement and location of stars, planets and other astronomical objects in the universe. Tides are also caused by the gravitational forces of the Earth and Moon.

With increase passive gravitational mass the force with which the gravitational fields of other bodies act on this body also increases.

Inert mass

Inertial mass is the property of a body to resist movement. It is precisely because a body has mass that a certain force must be applied to move the body from its place or change the direction or speed of its movement. The greater the inertial mass, the greater the force required to achieve this. Mass in Newton's second law is precisely inertial mass. The gravitational and inertial masses are equal in magnitude.

Mass and relativity

According to the theory of relativity, gravitating mass changes the curvature of the space-time continuum. The greater the mass of a body, the stronger the curvature around this body, therefore, near bodies of large mass, such as stars, the trajectory of light rays is bent. This effect in astronomy is called gravitational lenses. On the contrary, far from large astronomical objects (massive stars or their clusters called galaxies), the movement of light rays is linear.

The main postulate of the theory of relativity is the postulate about the finiteness of the speed of propagation of light. Several interesting consequences follow from this. Firstly, one can imagine the existence of objects with such a large mass that the second cosmic velocity of such a body will be equal to the speed of light, i.e. no information from this object will be able to reach the outside world. Such cosmic objects in the general theory of relativity are called “black holes” and their existence has been experimentally proven by scientists. Secondly, when an object moves at near-light speed, its inertial mass increases so much that local time inside the object slows down compared to time. measured by stationary clocks on Earth. This paradox is known as the “twin paradox”: one of them goes into space flight at near-light speed, the other remains on Earth. Upon returning from the flight twenty years later, it turns out that the twin astronaut is biologically younger than his brother!

Units

Kilogram

In the SI system, mass is expressed in kilograms. The standard kilogram is a metal cylinder made of an alloy of iridium (10%) and platinum (90%), weighing almost the same as a liter of water. It is kept in France, at the International Bureau of Weights and Measures, and its copies are throughout the world. The kilogram is the only unit that is determined not by the laws of physics, but by a standard made by people. The derivatives of kilogram, gram (1/1000 of a kilogram) and ton (1000 kilograms) are not SI units, but are widely used.

Electron-volt

Electronvolt is a unit for measuring energy. It is usually used in the theory of relativity, and energy is calculated using the formula E=mc², where E- this is energy, m- mass, and c- speed of light. According to the principle of equivalence of mass and energy, the electronvolt is also a unit of mass in the system of natural units, where c is equal to unity, which means mass equals energy. Electrovolts are mainly used in nuclear and atomic physics.

Atomic mass unit

Atomic mass unit ( A. eat.) is intended for masses of molecules, atoms, and other particles. One a. e.m. is equal to 1/12 the mass of a carbon nuclide atom, ¹²C. This is approximately 1.66 × 10 ⁻²⁷ kilograms.

Slug

Slugs are used primarily in the British Imperial system in Great Britain and some other countries. One slug is equal to the mass of a body that moves with an acceleration of one foot per second per second when a force of one pound-force is applied to it. This is approximately 14.59 kilograms.

Solar mass

Solar mass is a measure of mass used in astronomy to measure stars, planets and galaxies. One solar mass is equal to the mass of the Sun, that is, 2 × 10³⁰ kilograms. The mass of the Earth is approximately 333,000 times less.

Carat

Carats measure the weight of precious stones and metals in jewelry. One carat is equal to 200 milligrams. The name and the size itself are associated with the seeds of the carob tree (in English: carob, pronounced “carob”). One carat used to be equal to the weight of the seed of this tree, and buyers carried their seeds with them to check whether they were being deceived by sellers of precious metals and stones. The weight of a gold coin in Ancient Rome was equal to 24 carob seeds, and therefore carats began to be used to indicate the amount of gold in the alloy. 24 carat is pure gold, 12 carat is half gold alloy, and so on.

Grand

The grain was used as a measure of weight in many countries before the Renaissance. It was based on the weight of grains, mainly barley, and other popular crops at the time. One grain is equal to about 65 milligrams. This is a little more than a quarter of a carat. Until carats became widespread, grains were used in jewelry. This measure of weight is still used to this day to measure the mass of gunpowder, bullets, arrows, and gold foil in dentistry.

Other units of mass

In countries where the metric system is not adopted, the British Imperial system is used. For example, in the UK, USA and Canada, pounds, stones and ounces are widely used. One pound is equal to 453.6 grams. Stones are used mainly only to measure human body weight. One stone is approximately 6.35 kilograms or exactly 14 pounds. Ounces are primarily used in cooking recipes, especially for foods in small portions. One ounce is 1/16 of a pound, or approximately 28.35 grams. In Canada, which formally adopted the metric system in the 1970s, many products are sold in rounded imperial units, such as one pound or 14 fluid ounces, but are labeled with weight or volume in metric units. In English, such a system is called “soft metric” (English). soft metric), in contrast to the “rigid metric” system (eng. hard metric), in which the rounded weight in metric units is indicated on the package. This image shows "soft metric" food packaging with weight in metric units only and volume in both metric and imperial units.

Do you find it difficult to translate units of measurement from one language to another? Colleagues are ready to help you. Post a question in TCTerms and within a few minutes you will receive an answer.

In everyday life, we very often have to deal with measuring weight, be it our own weight or a purchased product. However, most often these are kilograms and grams. And in very rare cases - milligrams. Despite the apparent simplicity of the question, not every person will be able to immediately remember how many milligrams are in a gram. Although very often his life depends on the correct answer to this question.

What unit of measurement is called a gram?

Before remembering how many milligrams are in a gram, it’s worth brushing up on your knowledge of the gram. So, the gram is an SI unit for determining mass. Its homeland is France, hence the melodic name gramme.

The gram as a unit of measurement was introduced in the last decade of the eighteenth century.

By weight, it is equal to 0.001 kilograms, (0.000001 tons, 0.00001 centners) in other words, there are a thousand grams in one kilogram.

The gram is indicated by the letter “g” in the Cyrillic alphabet and the letter g in the Latin alphabet.

Like other SI units, grams are used to measure weight in science, technology and in everyday life in most countries of Europe and the world. However, in the United States and some other countries, weight is traditionally measured in pounds, which is approximately 0.45 kilograms. As in the old days, some countries have their own numerical equivalent for the pound, which is why there is confusion when converting to SI. Due to this situation, countries using pounds are gradually starting to switch to kilograms.

An interesting fact: Rus' also had its own pound, and it was slightly heavier than the modern one.

In the system of measuring weight in pounds, there is also a kind of analogue of a gram - an ounce (oz). It weighs 28.4 grams.

How many milligrams are in one gram

Kilograms, centners and tons are units of measurement that are larger than a gram. But there are also those that are smaller than it, the so-called “multiple units”. These include: milligram (mg-mg), microgram (mcg-mkg), nanogram (ng-ng) and pictogram (pg-pg). Apart from the milligram, all the others are rarely used in everyday life, since there is no particular need, and to measure them you need ultra-sensitive scales, which are not cheap.

The answer to the question of how many milligrams are in 1 gram is the number 1000, that is, one gram consists of a thousand milligrams, or there are 0.001 grams in one milligram.

Why do you need to know how many milligrams are in a gram?

A milligram is a tiny measure of weight, which at first glance seems unsuitable for measuring anything in everyday life. After all, no one will measure sugar or cereal in milligrams.

However, if a person feels unwell and needs medication, he begins to calculate the required dosage of the drug, he will immediately understand why it is important to know how many milligrams are in a gram. After all, many drugs are prescribed in relation to the patient’s weight. And if the sick child or teenager is sick, then the dose of the medicine should be small, most often less than a gram, so you need to clearly understand the gram/milligram ratio, otherwise you can cause irreparable harm to your health.

For example, while on vacation a child was bitten by a bee, the bitten area became swollen, which means it is necessary to take an antihistamine. However, in the travel first aid kit this medicine is only available in tablets. After reading the instructions carefully, you can understand that one tablet weighs 1 gram, but children weighing up to 10 kilograms can be given no more than 250 milligrams of the drug at a time. Having knowledge about the milligram, you can easily calculate the permissible dose: 1 g = 1000 mg, 1000/250 = 4, it turns out that the child can only be given a quarter of the tablet at a time.

In recent years, it has become fashionable to make your own skin care products.
Making so-called soap from scratch has become especially popular. Despite the simplicity of the process, it is important to follow the dosage exactly, otherwise you may get burned. After all, if you incorrectly calculate the proportion of oils and caustic soda, then either not all of the soda will interact with the oils and the remainder of it will get on the skin when using soap; Or there will be too much oil and the soap will not clean well.

Milligram and milliliter

When discussing the topic of milligrams, it is impossible not to mention the milliliter (ml). They are very often confused. It is worth remembering that weight is measured in milligrams, and volume in milliliters. So the liquid is measured only in milliliters, and the syringe scale is milliliter, not milligram.

Tablets and powders are always measured in milligrams.

These two measures are equal to each other in some cases; in other situations, you need to know the density of the liquid being measured in order to accurately calculate its weight.

Almost every day when shopping in a store, people have to convert kilograms into grams and vice versa, so this skill has become automatic. In the case of grams and milligrams, this is all done according to a similar scheme. Therefore, having learned how many milligrams are in a gram, you can then, if necessary, carry out these calculations yourself.

We often forget that we went to school and took a course in physical quantities and their units of measurement. Many people don’t even know how many milligrams are in a gram, and vice versa.

Why is this so important?

Let's first figure it out: where it is necessary to know this (mandatory), and how knowledge about grams and milligrams can someday be useful in the lives of each of us.

Medicine and industry

You simply cannot do without this knowledge when it comes to medical dosages, industrial and cosmetic proportions. Moreover, if we talk about medicine, then one cannot take values ​​lightly. After all, the lives of millions of people depend on it! The same is true in industry, where precision is important. Imagine if an arms factory worker did not know how many milligrams are in one gram of gunpowder. It’s scary to even speculate about what could happen due to a lack of knowledge about grams and milligrams.

In medicine, due to an error in the proportions of active substances, a medicine can become a deadly poison, even if half a milligram is too much or too little!

Unfortunately, there are more and more modern people who don’t even have a concept about the conversion (translation) of physical quantities. It is probably no longer a secret that such people can and have already ended up in the medical or industrial sphere, where it is impossible to do without it. There are also those who confidently say: “There are one hundred milligrams in one gram.” This applies not only to mass, but also to knowledge about other quantities. And who knows where they work? Such mistakes are fraught with accidents and disasters.

The SI system uses only kilograms for calculations. Even a small amount of mass is converted into kg. For example, 123 grams should be written as 0.123 kg.

Thanks to those people who are fluent in translating units of measurement of physical quantities, we are alive and have the opportunity to treat diseases and use other substances to make our lives easier. Pharmacists, for example, know how to dose medications correctly. Chemists who develop pesticides and fertilizers obtain effective drugs so that the harvest is good and pests do not destroy the crops. They, like no one else, know how many mg are in 1 gram.

Life situations

You have probably often heard from children who study at school, for example, the following words: “Why know this? I’ll be a policeman, but this won’t be useful to me in life!” In fact, it will come in handy.

Let's say you have to give medicine to an old grandmother. The instructions say that you need to take 250 mg twice a day. 250, no more and no less! Otherwise, the drug will begin to act incorrectly, cause side effects, or even an overdose. On the box of tablets there is an inscription: “The package contains 50 tablets of 1 g of active substance each.” The instructions do not say that you need to break the tablet into exactly four parts, but they say that you should take 250 milligrams. As you can see, you need to know how many milligrams are in one gram.

Or, cases with fertilizers, which are sometimes packaged in several grams. For example, a bag contains one gram of powder. To fertilize, say, an indoor flower, you need to dilute 500 milligrams in 200 milliliters of water. Again, they didn’t write that half a sachet should be diluted, namely 500 mg.

Hunting, the same case with gunpowder. Let's come up with a situation. A person does not buy ready-made cartridges, but loads them himself. Takes a kilogram of gunpowder. You need to pour, for example, 2.25 g into the cartridge. It has precise scales that show only in milligrams. He sits and thinks: “What should the milligram scales show me so that I put 2.25 grams into the cartridge?” It would be appropriate to know that the required mass of gunpowder should be 2250 milligrams on its scales. Of course, you can use special programs.

Such cases can be cited as examples endlessly. There is only one conclusion from this: whether you work in the field of precision industry or not, you should have knowledge of units of measurement in your head. It will still be useful.

How to calculate

Now let’s figure it out: how many mg are in 1 gram and vice versa. First of all, it is worth remembering that there are 1000 milligrams in one gram. And 1 milligram is one thousandth of a gram. That is, 1 mg is 0.001 g and 1 g is 1000 mg.

The main thing is not to make a mistake with zeros and correctly move the comma of decimal fractions:

• 1 gram = 1000 milligrams;
• 10 grams = 10,000 milligrams;
• 5 milligrams = 0.005 grams;
• 50 milligrams = 0.05 grams;
• 500 milligrams = 0.5 (half) grams.

Now we know how many milligrams make 1 gram. But if it’s the other way around, then you need to deal with decimal fractions. One zero is a move of the decimal place one place. If we want to write 1 milligram as grams, we get 0.001.

1 milligram is one thousandth of a gram. We divide 1 by a thousand, that is, we move the decimal point to the left by three places, since there are three zeros in a thousand. 10 milligrams is one hundredth of a gram (by two digits). 100 milligrams is one tenth (one digit).

For example, you have 24 milligrams. In grams it looks like this: 0.024 g. 24 is divided by a thousand. If from grams to milligrams, then zeros are added accordingly. 356 grams is 356,000 mg.

It's easier to work with comma wrapping. It's faster and you'll never make a mistake.

Practical calculation - video

Medicine is transported to the diseased organ in different ways. Sometimes in the form of a powerful volley - an injection, and sometimes - indirectly, if, for example, the medicine is administered orally (“per” - “through” + “or” - “mouth”). Be that as it may, the effectiveness of treatment and the likelihood of side effects largely depend on the dose administered.

A LITTLE ABOUT TERMS
The dose (concentration of the active substance) is most often indicated in grams or fractions of a gram (milligrams, micrograms, etc.).

Single dose- this is the amount of substance per dose.
Daily dose- amount of substance to be taken per day.
Therapeutic dose- the amount of a substance that causes a therapeutic effect.

Distinguish highest single dose(abbreviated as VRD) and highest daily dose(abbreviated VSD) - that is, such an amount of a substance, the intake of which will not cause serious consequences.

In addition, they distinguish maximum (highest), minimum or average therapeutic dose:
one that is below the minimum will not have a therapeutic effect;
that which exceeds the maximum is no longer a medicine, but a poison that has a strong toxic effect on the body, its tissues and organs.

Course dose- dose of the drug per course of treatment. This is especially true for antibiotics.

GENDER AND AGE MATTER
Often single and daily doses are indicated not by one number, but by some kind of limit.
Example:
... take 50-70 mg per dose. Daily dose 100-200 mg.
In this case, the minimum and highest therapeutic doses are indicated, or rather, their average values.

When prescribing a medicine, the doctor takes into account various factors:
patient's gender and weight;
patient's age;
severity of the disease;
interaction of the drug with other medications taken, etc.
For example, due to the characteristics of metabolism, men require larger doses than women, but adolescents and the elderly require smaller doses than in adulthood. People who are below average weight need a lower dose than those who are heavier. Etc.

The dose for children is usually prescribed in 2 ways:
by age (with the wording: take up to 2 months or up to 1 year, etc.);
by weight (indicate the amount of the drug per 1 kg of body weight - in mg/kg or mcg/kg).
Please note that the most accurate dosage calculation for both children and adults is relative to body weight!

Example:
Let's say the doctor ordered to give medicine to the child several times a day; single dose - 2-3 mg/kg.
If a child weighs 10 kg, then 20-30 mg of the active substance is needed for 1 dose.

Approximate calculation of dosages for children:
There is a table of approximate calculations of dosages for children relative to the adult dose. However, these calculations do not apply to potent drugs, the dosages of which are calculated in a more complex way!

Please note: for children it is better to use children's medications!
Firstly, it is difficult to ensure the accuracy of the dosage of a medicinal substance when dividing a tablet into several parts (even if the active substance is evenly distributed throughout the entire volume of the tablet, it is very difficult to accurately divide it into equal parts).
Secondly, for children's drugs, the requirements for tablet components (both medicinal and auxiliary) are much higher.

MEASURES FOR THE VOLUME OF LIQUIDS
1 teaspoon = 5 ml
1 dessert spoon = 2 teaspoons = 10 ml
1 tablespoon = 3 teaspoons = 15 ml
faceted glass = 200 ml
per 200 ml = 16 tablespoons = 20 dessert spoons = 40 teaspoons.

For accurate and accurate dosing of medications, it is best, of course, to use devices that act as a medical dispenser. These are measuring cups, dispensing spoons, dispensing pipettes - for dosed administration of liquid and powdered medications. As a rule, they allow dosing of drugs in the range from 2.5 to 60 ml and are quite acceptable for use at home.

It is clear that these devices are designed only for enteral routes administration of dosage forms, that is, entering the body directly through the digestive tract (most often orally - through the mouth). In all other cases (mainly in medical institutions), more complex dosing systems are used, which make it possible to control the dose and rate of drug administration, the duration of the effect, while facilitating the work of medical personnel and increasing the overall safety of the procedure, etc. These could be syringe dispensers for continuous drug administration or the most advanced microchip implants to date.

HOW MUCH MEDICINE IS IN A TINCTURE OR SOLUTION?
For liquid dosage forms, the dosage is often indicated per 1 teaspoon (5 ml).
Example:
The doctor prescribed me to take the medicine in the form of a syrup or suspension.
On the package or in the annotation it is indicated - 15 mg / 5 ml. This means that 1 teaspoon contains 15 mg of the drug.
Accordingly, if you are prescribed a single dose of 30 mg, then you should take 2 teaspoons of syrup at one time.

Often in liquid dosage forms the content of the drug is indicated throughout the entire volume of the solution or syrup.
Example:
The annotation states that the bottle contains 80 mg of the active substance, and the packaging is 160 ml.
In this case, it is recommended to take the drug 1 teaspoon 2 times a day.
Let's calculate the dose per 1 ml:
To do this, the dose of the substance in the entire volume must be divided by the entire volume of liquid. That is: 80 mg / 160 ml = 0.5 mg in 1 ml.
Knowing that a teaspoon holds 5 ml, we multiply the result by 5. That is: 0.5 X 5 mg = 2.5 mg.
Therefore, 1 teaspoon (single dose) contains 2.5 mg of active ingredient.

Sometimes the dose of the active substance is indicated relative to 100 ml or 100 mg. The calculations in this case are similar to the previous ones.
How to calculate if the dose is given per 100 g of liquid?
Example:
The annotation states that 100 g of the finished solution contains 40 mg of the active substance.
We take into account that 100 g is 20 teaspoons of 5 ml.
Now let's do the calculations:
divide the indicated dose of the substance (40 mg) by 20. That is: 40 mg / 20 = 2 mg.
Therefore, the dose of the drug in 1 teaspoon of the prepared solution is 2 mg.

STRICTLY ACCORDING TO THE RECIPE
The patient’s rapid recovery depends on the proper use of medications. This is why it is so important to strictly adhere to the indicated doses and time of administration - on an empty stomach or after meals. To be convincing, here are a few more calculations.

Example:
The annotation of the drug states that 1 tablet contains 30 g of active ingredient. Course dose - 800-900 g
The prescription states: take 1 tablet 3 times a day (for) 7 days.
Now we count: 30 g x 3 times = 90 g per day, or 90 g x 7 days = 630 g per course of treatment.
Therefore, the dosage in the recipe is underestimated. Be sure to ask your doctor why you should stick to this dosage!

WHAT TO DO IN THE EVENT OF OVERDOSE?
Dizziness, headache, nausea, vomiting, weakness, staggering gait - all these are the most noticeable symptoms of an overdose.
Adults urgently need to rinse their stomach and induce vomiting, drink strong tea (under no circumstances should you drink milk!) and be sure to call a doctor. If acute drug poisoning is suspected, urgent hospitalization of the victim is necessary, especially if a child is injured!
