More about mass

General information

Mass is a property physical bodies resist acceleration. Mass, unlike weight, does not change depending on 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- free fall acceleration. 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 the body (passive mass) and with 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 gravitational fields other bodies act on this body.

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 inert mass, the great strength you need to apply for 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 that the speed of propagation of light is finite. 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 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. e.m.) 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 equal to the mass of the Sun, that is, 2 × 10³⁰ kilograms. The mass of the Earth is approximately 333,000 times less.

Carat

Mass is measured in carats 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”). It used to be one carat equal to weight the seed of this tree, and buyers carried their seeds with them to check whether they had been deceived by sellers of precious metals and stones. Gold coin weight 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, showing 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 own weight or the product being purchased. 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, one 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 milligrams, you can easily calculate 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 cosmetics.
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.

After finishing school, many of us forget a lot of the material we have covered. And a simple question - “How many milligrams are in a gram” - often confuses people; the answer is not clear. However, the data useful knowledge are very necessary in our everyday life! And I will prove this using elementary everyday examples.

Look, the correct dosage of various constituent ingredients or components in cooking, cosmetology, and medicine completely depends on how diligently we have learned the systems for converting body weight from kilograms to grams, and from grams to milligrams.

Frivolous and dishonest attitude towards anyone production process will ruin the end result - obtaining a product of high quality in all respects, be it an anti-aging cream, a homemade dish or a medicine.

You need to initially figure out what, where and in what quantity you can add. Therefore, knowing how many milligrams are in a gram will be very useful to us in life.

How many milligrams are in one gram?

When working with substances of small volume, small component sizes are most often used. It is very important not to confuse the ratio of the constituent substances.

You know, even on the vastness of the World Wide Web of Information - the Internet, you can sometimes come across “brilliant” knowledge physical properties substances where “experts” claim that one gram supposedly contains 100 milligrams!

But imagine, when people read such posts, some of them are misled and make mistakes in their calculations, God forbid, if he is a pharmacist!

So, how many milligrams are in a gram, how to do the calculations correctly?

Remember that one milligram is one thousandth of a gram. The prefix "Milli" means 10 to the - 3 (minus third) power. It indicates one thousandth.

One gram consists of one thousand milligrams. Everything is very simple and without a calculator. It is quite enough to use the most basic knowledge from the field of arithmetic and physics.

Calculations, formula, examples, how to calculate

To make it easier to understand how many milligrams are in 1 gram, see this visual example:

1 gram equals 1,000 milligrams

Or vice versa:

1 milligram will equal 0.001 grams

From this it follows:

1 kilogram is equal to 1000 grams, this is equal to 1,000,000 milligrams

Using this simple table you can correctly calculate the amount of substances.

If you are going to make cosmetics and medications correctly, and strictly follow the recipes for their preparation, knowing how many milligrams are in one gram is very necessary!

You can independently understand all the nuances and subtleties of the culinary or pharmaceutical arts, but ignorance of a simple thing, how many milligrams are in a gram, will put you under very big question Your professional and amateur suitability in these areas of activity. You must correctly calculate the weight of components and ingredients and quickly find rational solutions.

Let's assume that you really need to be given an effective medicine small child. The dosage of all drugs is strictly different for adults and children. The most difficult task is to choose the right dose of medication to avoid side effects for the health of children under three years old, very young. Knowing the standard weight of a whole tablet and the amount of active substances in it, you can simply calculate remedy for the baby.

For example, the weight of a whole tablet is 500 milligrams (half of one gram). The pediatric dose of the drug is 0.25 grams. To calculate, we will use an elementary school formula; there are two ways to convert quantities - from grams to milligrams or vice versa. Here is the result:

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

You can do the opposite:

0.25 grams = 250 milligrams!

As a result, two figures are obtained in the calculation - 500 milligrams and 250 milligrams. Now it is easier to understand how to split the tablet correctly.

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

1. 0.12 grams = 120 milligrams.
2. 540 milligrams = 0.54 grams.
3. 0.03 grams = 30 milligrams.
4. 36 milligrams = 0.036 grams.

This way, you can simply deal with incomprehensible quantities. There is no need to divide or multiply if you correctly understand the number of zeros.

In the previous version (2) with 540 milligrams, 0.54 grams can be obtained by moving the separating comma three digits forward, which means three zeros in 1000. Do you remember, have you forgotten that there are 1000 milligrams in one gram? And in example (3), with the conversion of 0.03 grams to milligrams, the comma is moved back three digits and the missing zero is added. Here's an example: 0.030 = 30.

Note. Antibiotics are produced in ED (units of action), grams, milligrams and percentages. 1 g = 1,000,000 units. Antibiotics are dissolved with sterile water for injection, isotonic sodium chloride solution, 0.5% or 0.25% novocaine solution (if there is no history of allergic reaction). 1. Take a bottle, check the name of the antibiotic, dose, expiration date of the drug, and integrity of the bottle.
2. Wash and disinfect your hands, put on sterile rubber gloves.
3. Add solvent to the bottle. To dilute antibiotics, a dilution of 1:1, 1:2, 1:4 is used. Dilution is 1:1. a) Add such an amount of solvent into the bottle with the antibiotic that 1 ml of the solvent contains 100,000 units of antibiotic (or 100 mg of antibiotic).
For example:
- if the bottle contains 0.5 g, which is 500,000 units, to get 100,000 units in 1 ml, you need to take 5 ml of solvent;

How many milligrams are in 1 gram: calculation and answer

School ended a long time ago and basic knowledge They staggered a little. Not so much, of course, that you completely forget the metric values, but you can’t immediately answer how many mg are in 1 gram.

Restoring memory

From arithmetic we know that 1 g is a multiple of 1 kg, that is, a thousandth of a kilogram. And when you need to find out how many grams are in a kilogram, we multiply the number denoting kilograms by a thousand and get:

1 kg x 1000 = 1000 g, or 1 kg = 103 g.

So, a milligram is also a thousandth of a value called a gram.

And the problem is solved in a similar way when you need to find out how many milligrams are in it.

We assign three zeros to the number that denotes the amount of g.

1 g x 1000 = 1000 mg, or 1 g = 103 mg. Here is a simple answer to the question - how many mg are in 1 gram.

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.

I hope this information is useful and makes diabetic arithmetic easier for someone. Let's talk in this article about calculating the dose of insulin for diabetes.

Insulin dose calculation

Insulin is dosed in biological units of action (AU) and released in special vials. So, one 5 ml bottle contains 200 units of insulin (there is a corresponding marking on the bottle), respectively, 1 ml contains 40 units of the drug (200:5 = 40). It is better to inject a dose of insulin with a special syringe on which the units are indicated. When using regular insulin, before administering the drug, you need to find out how many units of insulin are in each division of the syringe. The calculation is made as follows: if 1 ml contains 40 units of an insulin dose, this amount is divided by the number of divisions in 1 ml of the syringe and the amount of insulin dose in one division is obtained. For example, there are 20 divisions in 1 ml of a syringe, therefore there are 2 units in one division (40: 20 = 2). In the case when the patient needs to administer 16 units, eight divisions are filled with the medicine...

You are trying to correlate incompatible things, to compare kilograms with kilometers. In this case, the activity of the drug “colllizin” with the weight of the cosmetic product “fermenkol”. Let's try to figure it out.

1. Collagenase is not an enzyme, but an enzyme preparation, its activity is expressed in action units (AU). 1 g of this drug must contain at least 500 units.

2. Collalysin is a medicine; it may contain, as you write, from 100 to 900 collagenase units (CU) per unit of the drug. And it doesn’t matter at all how many mg are in the drug. The more KE, the more concentrated and effective the medicine (it’s just that the patient’s scars may not require too high collagenase activity - there’s no need for an overdose, as with everything).

3. Fermenkol is not a medicine, but a cosmetic product. It does not contain collagenase, but collagenolytic proteases (this is no longer a drug, but actually enzymes that break down the 3-helical collagen molecule). There is activity in collagenase...

What is at diabetes mellitus The patient’s nutrition plays a decisive role, as many people know. Indeed, regulating the intake of carbohydrates from food greatly facilitates the selection of the correct dose of insulin. The principles of insulin action - science saves lives, but it is very difficult to calculate the required amount of certain foods every day, for many years, and everything that is difficult is usually ignored by people. That is why the concept of “bread unit” was introduced, which made it easier to calculate nutrition for millions of people suffering from one form or another of diabetes.

What is a bread unit

Bread unit (XU) is a measure of carbohydrates in foods. One bread unit is equal to twelve grams of sugar, or twenty-five grams of black bread. A certain amount of insulin is spent on the breakdown of one unit of bread, on average equal to two action units in the morning, one and a half units in the afternoon, and one action unit in the evening.

Well, why wash it - what if someone else is interested?
Insulin activity is measured in action units (AU) or, which is the same in this case, in international action units (IU - Russian or IU - English or UI - French). 1 unit corresponds to the activity of 1/24 mg (41.66 μg) of crystalline insulin. There is no difference because the USSR once accepted international units no changes.
The history of the formation of the insulin action unit is interesting. Frederick Banting in 1922 proposed to consider the unit of insulin action to be the number of cubic centimeters of pancreatic extract that, within 2-4 hours, brought a healthy rabbit to hypoglycemia with a CK level of 2.5 mmol/l. In everyday life, scientists began to call this unit “rabbit”. A little later that year (apparently they ran out of rabbits), the same team proposed a “mouse” unit - the amount of insulin required to bring half of the experimental group of mice into convulsions...

1 mg is how many grams, for different substances differently

Milliliters are volume and grams are weight:

how to convert milligrams to milliliters

1 kilogram = 1 liter, 1 gram = 1 milliliter (for water), and mg is a thousandth of a gram

1 ml water = 1000 mg water = 1 gram water

1 ml water = 1 gram water

1 ml of gasoline = approximately 0.74 grams

Use the formula: m = P x V

where m is mass, measured in kilograms (1 g = 0.001 kg)

P - density of the substance (kg/l)

V - volume (liters, 1 ml = 0.001 l)

in order to find out how many grams are in 1 ml of a substance, you need to find out its density and multiply by volume; for water there is no need to count, because 1 ml of water = 1 gram of water

Density examples:

milk -1.03 grams (1027-1032 kg/m3)

olive oil - 0.92 grams

machine oil - 0.91 grams

vegetable oils - 0.86 - 0.98 g/cm3

Liquid volume measures

1 teaspoon = 5 ml.

1 dessert spoon= 2 teaspoons = 10 ml.

1 tablespoon = 3 teaspoons = 15 ml.

Example: 1

Composition - 15 mg / 5 ml. (indicated on the package or in the instructions) This means that 1 teaspoon contains 15 mg. medicine.

If you are prescribed a single dose of 15 mg, then you should take 1 teaspoon of syrup at one time.

If you are prescribed a single dose of 30 mg, then you should take 2 teaspoons of syrup at one time.

Example: 2

The bottle contains 80 mg / 160 ml, where 80 mg is the active ingredient. In this case, it is recommended to take the drug 1 teaspoon 2 times a day.

We calculate the dose of 1 ml: for this, the dose of the substance in the entire volume must be divided by the entire volume of liquid:

Divide 80 mg by 160 ml = 0.5 mg per 1 ml.

Since a teaspoon holds 5 ml, we multiply the result by 5. That is: 0.5 mg X 5 = 2.5 mg.

Therefore, 1 teaspoon (single dose) contains 2.5 mg. active substance.

Example: 3

The instructions indicate that 60 ml of the finished solution contains 3000 mg of the active substance.

And 60 ml is 12 teaspoons of 5 ml.

Now let’s do the calculations: the indicated dose of the substance is 3000 mg. divide by 12. That is: 3000 mg / 12 = 250 mg.

This means that 1 teaspoon of the prepared solution is 250 mg.

Example: 4

100 mg. The active substance is contained in 5 ml.

In 1 ml. contains: 100 divided by 5 = 20 mg. active substance.

You need 150 mg.

Divide 150 mg by 20 mg - you get 7.5 ml.

DROPS

1 ml. aqueous solution – 20 drops

1 ml. alcohol solution - 40 drops

1 ml. alcohol-ether solution – 60 drops

STANDARD DILUTION OF ANTIBIOTICS FOR INTRAMUSCULAR ADMINISTRATION

1 mg = 1000 mcg;

1 mcg = 1/1000 mg;

1000 mg = 1 g;

500 mg = 0.5 g;

100 mg = 0.1 g;

1% corresponds to 10 g/l and 10 mg/ml;

2% 20 g/l or 20 mg/ml;

1:1000 = 1 g/1,000 ml = 1 mg/ml;

1:10,000 = 1 g/10,000 ml = 0.1 mg/ml or 100 μg/ml;

1:1,000,000 = 1 g/1,000,000 ml = 1 μg/ml

If a solvent is not provided in the package, then when diluting the antibiotic by 0.1 g (100,000 units) of powder, take 0.5 ml. solution.

Thus, for breeding:

0.2 g. 1 ml needed. solvent;

0.5 g. You need 2.5-3 ml. solvent;

1 g. need 5 ml. solvent;

Example: 1

The bottle contains 0.5 g of dry medicine. How much solvent do you need to take in 0.5 ml? the solution contained 0.1 g of dry matter.

When diluting the antibiotic by 0.1 g of dry powder, take 0.5 ml. solvent, therefore:

0.1 g of dry matter – 0.5 ml. solvent

0.5 g of dry matter - X ml. solvent

Answer: in 0.5 ml. the solution was 0.1 g of dry matter, you need to take 2.5 ml. solvent.

Example: 2

The bottle contains 1,000,000 units of dry medicine. How much solvent do you need to take in 0.5 ml? the solution contained 100,000 units of dry matter.

100,000 units of dry matter – 0.5 ml. dry matter

1,000,000 units – X ml. solvent

Answer: so that 0.5 ml of solution contains 100,000 units. dry matter you need to take 5 ml. solvent.

Example: 3

The bottle contains 0.25 g of dry medicine. How much solvent do you need to take in 1 ml? the solution contained 0.1 g of dry matter.

1 ml. solution – 0.1 g.

X ml. - 0.25 g.

Answer: in 1 ml. The solution was 0.1 g. You need to take 2.5 ml of dry matter. solvent.

Example: 4

The patient needs to administer 400,000 units. penicillin. Bottle of 1,000,000 units. Dilute 1:1.

How many ml. solution must be taken.

When diluted 1:1 in 1 ml. the solution contains 100,000 units. 1 bottle of penicillin, 1,000,000 units. dilute 10 ml. solution.

If the patient needs to administer 400,000 units, then 4 ml should be taken. the resulting solution.
