What is the difference between three milligrams and three milliliters

The milligram is a unit of weight and the milliliter is a unit of volume, and there is a qualitative difference between the two.

Milligrams and milliliters of the same object can be converted, and to convert volume units to mass units, it depends on the density of the substance, according to the formula: mass = volume * density.

For example, water, 1 mg of water is converted to milliliters, it is based on the density of water is 1g cm, 1 mg = gram, then, that is, 1 mg of water is milliliters.

One is a unit of weight and the other is a unit of capacity.

3 ml is 3 grams of water. Generally, the density of water is 1 gram of milliliters, so 3 milliliters of water is about 3 grams. Two different units cannot be converted directly. The milliliter is a unit of volume.

The gram is a unit of mass, and the way of unit conversion is different, and the conversion of milliliter and gram, Bifu needs to know the density, and the density of each thing is different. A milliliter is a unit of volume, 1 liter is equal to 1000 milliliters, and the milliliter symbol is represented by ml.

A gram is a unit of mass, 1kg = 1000g, a gram is a thousandth of a kilogram, and the symbol is represented as g. To convert according to the formula m=pv, i.e. mass is equal to density multiplied by volume. For example, if we know that the density of gasoline is, suppose we round the density of gasoline, so the mass of gasoline with a volume v of 3ml is m=, that is, the mass of 100 ml of gasoline is.

3ml is about 1 cap, but it depends on the size of the cap. Milliliters and grams are different units and cannot be converted. 3ml of water is 3 grams.

The total blood volume of a healthy adult accounts for 7%-8% of body weight, which is about 4000 to 6000 ml. Daily blood donation is generally 200 400ml, and when we do blood testing, take 8 tubes as an example, 1 tube is calculated as 3ml, the total amount is 24ml.

This amount does not cause any harm to the body. The blood of the human body is constantly metabolized, and many blood cells are aging and dying all the time, and a large number of new cells are produced at the same time to maintain the balance of the body's metabolism. Therefore, it seems that several tubes of blood have been drawn, but this amount will not affect our body, and there is no need to eat and drink a lot to replenish nutrients.

Unit conversion: 1L = 1000ml 1000ml 1000 cubic centimeters = 1 cubic decimeter.

1 ml of 1 sissy (cc).

1 ml liquid water 1 cubic centimeter of liquid water.

1 ml of liquid water weighs 1 gram at 4 degrees Celsius.

1 ml 1 cubic centimeter.

Three milliliters of liquid is about 15 drops. There are many common liquids such as water, wine, various beverages, etc. Plain water is the most reputable drinking water that meets the needs of the human body.

American scientists have found that when the boiled self-shielding water is cooled to 25 30, the chlorine content is the lowest, and the biological activity of the water is also increased, and it is easy to penetrate the cell membrane.

It can promote the body's metabolism, enhance immune function, and improve the body's ability to resist diseases.

Sweet drinks, functional drinks.

Fruit juice, strong tea.

Coffee, etc., is not a complete substitute for drinking water. Zhao Feihong said that all kinds of sweet drinks and fruit juices are high-sugar and high-calorie drinks, and the human body needs to consume more water to complete metabolism, and cannot replenish water well. Functional drinks, strong teas and coffee, all contain caffeine, which itself has a diuretic effect and is not conducive to hydration of the human body.

Office workers can replenish 200 ml of water in time after arriving at the company every day, which is conducive to promoting brain activity and concentration at work. In addition, office workers sit indoors for a long time and are prone to gain weight, so drinking 200 ml of water half an hour before a meal is conducive to increasing satiety and reducing the amount of food eaten to a certain extent.

Three taels is about 150 ml. Taking water as an example, 1 liter is equal to 1000 ml is equal to 1kg is equal to 20 taels, so three taels is about 150 ml.

The milliliter is a unit of volume, which corresponds to the cubic centimeter, and the main unit of the volumetric unit is liters (l). 1L = 1000ml, 1ml = 1 cubic centimeter, 1000ml = 1 cubic decimeter = 1L. Grams and milliliters are two different units and cannot be directly converted between them.

The conversion must know the density of the liquid, and the conversion is based on the density of the liquid. gram, is the unit of mass, symbol g. One gram is the mass of 18 14074481 C12 atoms.

One gram weighs about the same as one cubic centimeter of water at room temperature.

Mass and volume units should not be confused, because the density of the liquid is not the same, and it can be calculated according to water, because the water density is 4 = 1g cm, and 1 gram of water is 1 ml.

Unit Conversion:

1l = 1000ml 1000ml = 1000 cubic centimeters = 1 cubic decimeter; 1 ml of 1 sissy (cc). 1 ml liquid water 1 cubic centimeter of liquid water. 1 ml of liquid water weighs 1 gram at 4 degrees Celsius. 1 ml 1 cubic centimeter. 1 imperial fluid ounce = milliliter (1 5 imperial fluid and ear); 1 US fluid ounce = milliliter (1 4 US and ear).

3 ml.

ml, milliliter, unit of measure.

When the unit of measurement is expressed in letters, in general, the unit symbol letters are lowercase; When the unit ** is used in the name of a person, the first letter of the symbol must be capitalized.

There are volume units only.

l" is special, this symbol can be written as an uppercase l, or it can be written as a lowercase l. This is because the symbol for "liter" was originally lowercase, due to the lowercase l with Arabic numerals.

1 It is difficult to distinguish, and later the International Conference on Weights and Measures made a resolution that the symbol of "liter" can be written as an uppercase l, so that in the case that lowercase has not been abolished, both upper and lower case are used.

This is the International System of Units.

is the only symbol that is not named after a scientist and can be capitalized. In accordance with the requirements of the International Authority, the letter used to denote milli (10 -3) is "m" and should not be mixed with the letter "m" for mega (10 6).

So 3ml is 3ml.

Origin of the ounce:

1. The earliest is to drink different wines, choose different wine glasses, the capacity of the glass is the most important, and the ounce (English is ounce, abbreviated as oz) was used as the liquid unit of wine in history. Both the British and American systems of units have this unit, which is slightly different, such as the British 1 ounce; 1 ounce in the US is equivalent to 1 pint (US).

2. The International System of Units, the capacity of the barware is expressed in milliliters. 30ml instead of the original 1 ounce volume.

3. "Ounce" is the most commonly used unit of measurement in the world.

4. One ounce is about equivalent to the old weights and measures in China.

16 taels for a pound) a tael.

5. Ounce generally refers to a unit of weight.

Due to the different objects to be weighed, the weight of an ounce volume is also different, and gradually unified according to the industry has different weights. Such as: troy ounce (commonly used in the measurement of gold and silver), medicine balance ounce, textile ounce, constant balance ounce, etc.

Summary. Hello, if we want to find the volume of a liquid, we need to know its density, and we can get the volume by dividing the weight by the density, can you easily say what is the density of this liquid? In that case, I'll do the math for you. 殺

Hello, if we want to find the volume of the liquid Qi Feng in the high chain, we need to know its density, and we can get the volume by dividing the weight by the density that is now known, can you easily say what the density of this liquid is? In that case, I'll do the math for you. 殺

Don't know the density.

This one is required above.

Hello, if it's this kind of thing, you can see from the ** that it actually contains the main substance is water, so it and the density of water potato silver is basically the same as the hand, the first three grams of words is about three milliliters. 殺

This measuring cup cup is not.

Is it this cup?

Hello, your measuring cup is 30 ml, you look at the bottom of the line there is a 5 ml search tape grip scale, and then in the 5 ml scale in the five grids to choose three grids on the World Day

If it's water, it's 1, 30,000 milligrams is 30,000 milliliters.

Milligrams are units of mass, milliliters are units of volume, and there is a formula between them: mass = volume * density, a substance with a density of 1, and the weight of 1 milliliter is 1 milligram, such as water.

The unit of weight has a long history, in ancient times, each country has its own unit of measurement, the weight unit of the ancient Chinese vertical min, Jun: 30 catties is a jun; Ten taels weigh one baht, twenty-four baht weighs one tael, and sixteen taels weigh one catty. China has a specific unit of measurement, catty, the international unit of measurement, kilograms, tons, the United States stool fiber register of the United Kingdom, pounds and so on.

Volume is generally calculated in volumetric units, such as liters and milliliters, but is sometimes used in conjunction with volume units. Since the largest unit of volume is "liter", the common unit of volume is "cubic meter" when calculating the volume of a larger object.

1 liter (l) = 1000 milliliters (ml) (volume unit) 1000 grams (g) = 1 kilogram (kg) = 1 kilogram = 2 catties (weight unit) depends on the density of the liquid, for example: water The ratio is 1: 11 ml = 1 cubic centimeter = cubic decimeter, 1 kilogram = 2 kilograms, and the density of water is 1 gram cubic centimeter = 1 kilogram cubic decimeter = 1000 kilogram cubic cubic meter.

So 1000 ml of water = 1 cubic decimeter of water = 1 kg of water = 2 catties of water Summary: 1 liter of water 1 kilogram or kilogram.

Most of the mineral water we drink is liters (kg) or 2 liters (2kg).

It's the volume size of three cubic centimeters, and centimeters always have a concept.
