With this online calculator, you can convert milligram to milliliter. This is a simple program for converting milliliters into milligrams.

**How convert milligram to milliliter?**

Use the following formulas to calculate:

1) Volume = Weight / Density

2) Weight = Volume * Density

3) Density = Weight / Volume

__Example 1:__

How convert 100 milligrams water to milliliters?

If Weight = 100 mg

And Density = 1 g/cm3 (or 1000 mg/ml)

Then Volume = 100 / 1000 = 0.1 ml

__Example 2:__

How convert 2 ml milk to mg?

If Volume = 2 ml

And Density = 1.03 g/cm3 (or 1030 mg/ml)

Then Weight = 1030 * 2 = 2060 mg

__Example 3:__

How to determine air density?

If Volume = 1 ml

And Weight of this volume = 1.225 mg

Then Density air = 1.225 / 1 = 1.225 mg/ml

__Theory:__

Weight is a characteristic of the body, which is a measure of the gravitational interaction with other bodies.

Volume is a quantitative characteristic of the space occupied by a body or substance.

Density is a measure of mass per unit of volume.

Weight and volume depend on temperature, pressure and composition due to density changes.

**Reference data:**

Density of water = 1 g/cm3

Density of steel = 7.8 g/cm3

Density of concrete = 0.5 ... 2.5 g/cm3

Density of sand = 1.5 ... 1.8 g/cm3

Density of stone = 1.3 ... 3.8 g/cm3

Density of garbage = 0.16 ... 0.64 g/cm3

Density of ground = 1.2 ... 2.0 g/cm3

Density of paint = 0.9 ... 1.6 g/cm3

Density of air = 0.001225 g/cm3

The density of all materials (gas, metal, acids, salts and other) in this table.
