More about mass
General information
Mass is the property of physical bodies to 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- 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 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 get into external 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 kilogram is determined based on the exact numerical value of Planck's constant h, equal to 6.62607015×10⁻³⁴, expressed in J s, which is equal to kg m² s⁻¹, with the second and meter being determined by exact values c and Δ ν Cs. The mass of one liter of water can be approximately considered equal to one kilogram. 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. 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 Earth's mass is approximately 333,000 times smaller.
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 a seed from this tree, and buyers carried their seeds with them to check whether sellers had deceived them 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 karat is pure gold, 12 karat 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 for measuring 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.
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.
Putting knowledge into practice
Life constantly confronts us with a situation where we have to solve similar arithmetic problems. Most often, this occurs when taking medications.
For example, if the instructions for use say that you cannot take more than 0.2 g of the drug per day, and the tablets in the blister indicate the weight of 25 mg, then you need to find out how many tablets you can use.
Solution algorithm: 0.2 g x1000=200 mg, 200 mg:25 mg=8 tablets.
But the reverse conversion from milligrams to grams is also often found, especially when cooking or for chemical solutions for economic purposes.
We remember that if 1 g = 103 mg, then 1 mg = 10-3 g or 1 mg = 0.001 g.
Suppose, according to the recipe, we need to add 300 mg of granulated sugar and 800 mg of salt somewhere, and our scales only measure g.
International unit (IU)- in pharmacology, a unit of measurement of the amount of a substance based on biological activity. Used for vitamins, hormones, some drugs, vaccines, blood components and similar biologically active substances.
How many milligrams are in a gram?
Despite its name, IU is not part of the international measurement system SI.
The precise definition of a single IU varies for different substances and is established by international agreement. The World Health Organization's Biological Standardization Committee provides reference materials for certain substances, (arbitrarily) specifies the number of IUs they contain, and defines biological procedures for comparing other materials with the standards. The goal of such procedures is to ensure that different preparations having the same biological activity contain equal numbers of IU units.
For some substances, mass equivalents of one IU were eventually established, and measurement in these units was officially abandoned. However, the IU unit may still remain in widespread use because of convenience. For example, vitamin E exists in eight various forms, distinguished by their biological activity. Instead of accurately indicating the type and mass of the vitamin in the preparation, sometimes it is convenient to simply indicate its quantity in IU.
Wikipedia
International unit (IU)— internationally agreed standards necessary to compare the content of different biological compounds tested on the basis of their activity.
If cleaning is not possible chemical methods the substance is analyzed biological methods, and a stable standard solution is used for comparison. Serum standards are stored in State Institute whey (Copenhagen, Denmark), in National Institute medical research(Mill Hill, UK) and at the World Health Organization (WHO) (Geneva, Switzerland).
International unit established in the form of a certain amount of standard solution (for example, one IU of tetanus antitoxin = 0.1547 mg of standard solution, which is stored in Copenhagen).

How much is 5 milligrams?
What is the difference between 5 mg and 5 ml?
People quite often confuse the two completely different concepts: milliliter and milligram. Some people think they are the same thing. So let's figure it out.
To begin with, you need to determine which dosage form in front of us.
Solids are dosed by mass (weighed), and liquids are dosed by volume (measured).
In the first case, the unit of measurement is gram\milligram\microgram, and in the second - liter\milliliter.
Dosing by weight
Weight designations :
1.0 - 1 g (gram)
0.001 - 1 mg (milligram)
0.000001 - 1 mcg (microgram)
Measuring weights, weights, scales (based on the principle of weighing there are: spring, lever, manual, plate and others).
Measuring tools for the consumer: measure of measurement in in this case will be the dosage of the drug prescribed by the doctor. We talked about dosages in more detail in article.
Dosing by volume
Volume designations:
1 ml - 1 milliliter
1 l - 1 liter
MeasuringTools for the manufacturer: measuring and pharmaceutical pipettes, volumetric flasks, cylinders, beakers, burettes.
Measuring tools for the consumer: caps, pipettes, syringes, cups, measuring spoons.
Let's fix:
What does the designation say? 1,0 ?
Answer: This is the mass of a substance weighing 1 gram.
Clarification: If we are talking about the volume of the dosage form, then next to it there will be a designation - ml, that is 1.0 ml(or simply 1 ml).
How to calculate the required number of drops?
A non-standard unit of volume is a drop.
How many milligrams are in 1 gram?
This is an inaccurate indicator for calculations, because the volume of a drop depends on physical properties dosed liquid.
For comparison: volume of 1 drop alcohol solution averages 0.02 ml, and aqueous solution can range from 0.03 to 0.05 ml.
Pharmacists and doctors decided to jointly designate a standard measure for this unit of measurement. It is generally accepted that the volume of 1 drop is 0.05 ml.
When the dosage of a drug in drops is prescribed, it is assumed that the volume of one drop is 0.05 ml. If you have a 1 ml medical syringe at home, then you can easily determine the required volume of medicine: 2 drops - 0.1 ml, 3 drops - 0.15 ml, 5 drops - 0.25 ml.
Spoons are also an imprecise measuring device for determining the volume of a dosage form. Volume conventions are also adopted for them.
Reminder when dosing liquid dosage forms:
1 drop (drop) = 0.05 ml
2 drops = 0.1 ml (measured with a 1 ml syringe)
20 drops (pipette) = 1 ml
1 tsp (teaspoon) = 5 ml
1 d.l. (dessert or baby spoon) =10 ml
1 tbsp. (tablespoon) = 15 ml
1 tbsp. (glass) = on average 200 ml (glasses come in different capacities: from 110 to 320 ml)
In a future episode, you will learn how to define content active substance V dosage form, and how to calculate single/daily doses of the drug.

Quick answer: 1 g - 1000 mg.
Whatever you say, we tend to forget some information from school, especially if we never encounter it throughout our lives. For example, do you remember how many milligrams are contained in 1 gram?
How many milligrams are in one gram?
It’s good if you remember, but there are people who have forgotten this information. Let's not blame them - a person is not able to store in his head all the data that he once received. But we will answer the question.
Milligram is a unit of measurement of mass in international system SI units. A milligram is one thousandth of a gram (or one millionth of a kilogram). It turns out that 1 g of the substance contains 1000 mg. 1 milligram, in turn, contains 0.001 g of the substance.
Is it easy to remember?
Quite. However, in practice, we often encounter cases that often lead us into a stupor. A simple example: you need to take a pill. The packaging says that the weight of each tablet is 0.25 g, while you need to take 750 mg. Since we already know that one gram contains a thousand milligrams, we will simply convert the values. So, 0.25 g is 250 mg. We divide the prescribed 750 mg by 250 mg and get the number 3. Three - that’s exactly how many tablets you need to take.
Of course, you can translate everything back. 750 mg is 0.75 g. A tablet weighs 0.25 g. Divide 0.75 g by 0.25 g and get the same figure - 3. As you can see, everything is quite easy and simple, but if you have any questions on this topic, you can ask them to us using the comment section.
When working with small quantities of a substance, the unit of mass used is often the milligram (mg). A milligram is a thousandth of a gram. that is, one gram contains one thousand milligrams. To convert grams to milligrams you don’t even need a calculator – just basic knowledge of arithmetic.
Instructions
1. To convert a gram to a milligram, multiply the number of grams by 1000. That is, use the following primitive formula: Kmg = Kg * 1000, where Kmg is the number of milligrams, Kg is the number of grams. So, say, the mass of one tablet activated carbon– 0.25 grams. Consequently, its mass, expressed in milligrams, will be: 0.25*1000=250 (mg).
2. If the number grams is an integer, then to convert grams to milligrams, simply add three zeros to the right of it. Say, one tablet ascorbic acid with glucose weighs 1 gram. This means its mass in milligrams will be: 1,000.
3. If the number of grams is expressed as a decimal, move the decimal point three digits to the right. Let's say the content of glucose in one tablet of ascorbic acid with glucose is 0.887 grams. Consequently, in milligrams the mass of glucose will be 887 mg.
4. If there are less than 3 digits after the comma, complete the missing characters with zeros. So, say, the table of contents of ascorbic acid in one tablet of ascorbic acid with glucose is 0.1 grams. In milligrams it will be 100 mg (according to the rule, it turns out to be 0100 mg, but insignificant zeros on the left are discarded)..
5. If all the initial data are given in grams, and the result needs to be presented in milligrams, then carry out all intermediate calculations in grams, and convert only the result of the calculations into milligrams. So, let’s say, one tablet of allochol contains: - dry bile – 0.08 g - garlic dried – 0.04 g - nettle leaves – 0.005 g, - coal activated - 0.025 g. In order to calculate how many milligrams of energetic substances are contained in one allochol tablet, add up the masses of all components, expressed in grams, and convert the result into milligrams: 0.08 + 0.04 + 0.005 + 0.025 = 0.15 (g ).0.15*1000=150 (mg).
Gram is a unit of measurement of mass belonging to the metric system. Gram is one of the basic units of the GHS system of unconditional measures (centimeter, gram, second) - widely used before the adoption of the International System of Measurement (SI). Denoted as g or g.
How many milligrams are in one milliliter?
Its multiple unit of measurement of mass kilogram is one of the basic SI units, denoted kg or kg.
Instructions
1. Gram equal to the mass of one cubic centimeter of water at the temperature of its maximum density (4°C). As a measure of body mass, the gram is a derived unit in the metric system. It is one thousandth of the rod unit of mass - kilogram A. A kilogram was defined (with an accuracy of 0.2%) as the mass of one cubic decimeter (0.001 cubic meter) of water at the temperature of its highest density. Currently, to determine mass kilogram and the International Bureau of Weights and Measures in Paris maintains the standard kilogram a is a cylinder about 39 mm high, produced from a platinum-iridium alloy in 1889.
2. Gram equal to one thousandth kilogram a (1 g = 0.001 kg), therefore, to convert the known body weight, which is given in grams, you need to multiply it by 1000.

Note!
The conversion of grams to milligrams is used mainly in calculations related to the preparation of drugs and their dosage. When making calculations, be very careful - a mistake of one decimal place will lead to a tenfold error.

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.
Quite often in Everyday life(in the kitchen, in the garage, in the country house) we have to convert milligrams to milliliters. In fact, this translation usually does not cause difficulties. Although, people often confuse these two quantities, and often put an equal sign between them. This should absolutely not be done, especially when it is necessary to calculate the dosage of the medicine. Let's take it in order.
What is 1 milligram
A milligram is an international measure of the weight of any substance from gaseous to solid. Used in Russia and most other countries. One 1 milligram (mg) is equal to one thousandth of a gram and one millionth of a kilogram.
What is 1 milliliter
A milliliter is an international measure of volume; in everyday life it is most often used to measure liquid and bulk products. In medical slang it is called a “cube”. One milliliter is equal to one cubic centimeter and one thousandth of a liter.
How to convert milligram to milliliter
Often, the conversion of milligrams to milliliters is made for liquid, sometimes granular, substances.
To do this, you need to know their density.
What is density
Density or specific gravity is a physical quantity that reflects the ratio of mass to volume of a substance, usually denoted by the letter R(r). In everyday life, density is often expressed in grams per cubic centimeter (g/cm3) or grams per liter (g/l). Specific gravity clean water, for example, is equal to 1 g/cm3. or 1000 g/l.
Density table
To convert milligrams to milliliters we need such a table and a calculator. We take the density value of any substance, expressed in g/cm3. We make the calculation using the formula:
Vml = Qmg x R / 1000, Where:
- Vml - volume of material in milliliters.
- Qmg is the weight of the material in milligrams.
- p - density of the material in grams/cm3.
For example, we need to determine what volume in milliliters 10 mg of honey has.
We find the required substance in the table and determine its density. Honey density is 1.35 g/cm3. Substitute into the formula:
Vml = 10 x 1.35 / 1000 = 0.0135 ml. Accordingly, 1 mg of honey will occupy a volume of 0.00135 ml.
If you have a table of density at hand, expressed in grams per liter, you need to use the following formula:
- Vml = Qmg x R / 1000000.
It may be necessary to perform the opposite action - convert milliliters to milligrams. For this we again need a table and a calculator. The formula for calculation will now look like this:
- Qmg = Vml x p x 1000 - for density expressed in grams per cubic centimeter.
For example, we need to find out how much 75 ml of alcohol weighs in mg.
We turn to the table, find the density of the desired substance in g/cm cube, and substitute the values into the formula:
- Qmg = 75 ml x 0.80 X 1000 = 60000 mg.
If the density values in the table are indicated in grams per liter, then the formula will look like this:
- Qmg = Vml x R.
For our example it will be:
- Qmg = 75 ml x 800 = 60000 mg.
If you don’t have any tables at hand, you can determine the density of the substance yourself. To do this, you will need scales (the more accurate, the better), measuring utensils and a calculator.
As a measuring vessel, you can use any container with a known volume - a glass jar, a cut glass, a measuring cup, etc. For liquid products with a small volume (up to 20 ml), you can use a medical syringe.
Your task is to measure the volume as accurately as possible with a measuring container in milliliters and weigh the measured substance in grams. Next, you should divide the weight of the product by the volume. As a result, you will get the density:
- p= Qmg / Vml.
When cooking, great precision is not needed, so you can use a volume measure such as a spoon. It is known that the volume of a tablespoon is approximately 15–18 ml, and the volume of a teaspoon is about 6 ml. Now it remains to find out how much this volume weighs. Let's look at the table:
| Name | Tablespoon (mg) | Teaspoon (mg) |
| Jam | 18000 | 5000 |
| Salt | 30000 | 10000 |
| Powdered sugar | 25000 | 9000 |
| Flour | 25000 | 8000 |
| Oatmeal | 18000 | 5000 |
| Millet, buckwheat, rice, pearl barley | 25000 | 8000 |
| Oat flakes | 14000 | 4500 |
| Pressed yeast | 45000 | 15000 |
| Dry yeast | 16000 | 5000 |
| Citric acid | 25000 | 8000 |
| Powdered milk | 20000 | 5000 |
| Condensed milk | 35000 | 12000 |
| Soda | 29000 | 14500 |
| Ground pepper | 20000 | 6000 |
| Egg powder | 16000 | 6000 |
| Tomato paste | 30000 | 10000 |
| Cream | 14000 | 5000 |
| Milk | 18000 | 6000 |
| Kefir | 18000 | 6000 |
| Sour cream | 18000 | 6000 |
| Melted margarine | 20000 | 6000 |
| Ghee butter | 25000 | 6500 |
| Vegetable oil | 25000 | 6500 |
| Cognac | 18000 | 6000 |
| Vinegar | 16000 | 5500 |
It should be noted that the table shows the weight of spoons filled to the brim with liquid products, while bulk ones were filled with a small slide.
When taking liquid medicines often use a volume measure such as a drop. For example, the volume of 1 drop of an alcohol-based solution is 0.02 ml, and about 0.05 ml for a water-based solution. The medical measure of the volume of a drop is 0.05 ml. Below is a table of the number of drops of liquid medicines in 1 g, 1 ml and the mass of 1 drop in mg:
| Name | Weight of 1 drop in mg | Drops in 1 g | Drops in 1 ml |
| Hydrochloric acid, diluted | 50 | 20 | 21 |
| Adoniside | 29 | 35 | 34 |
| Medical broadcast | 11 | 87 | 62 |
| Hawthorn extract | 19 | 53 | 52 |
| Distilled water | 50 | 20 | 20 |
| Buckthorn extract | 26 | 39 | 40 |

In our video materials you will find a lot useful information about the mass and volume of various substances.
We often forget that we went to school and took a course 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 you need to know this (in 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 we 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, modern people, who even have no idea about the conversion (translation) of physical quantities, more and more. 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 receive 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 and 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, let's say 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 measurements 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 decimals. 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.
