With this online calculator, you can convert tonnes to m3 (tonnes to cubic meters). This is a simple program for converting cubic meters into tonnes.

See also - convert tonne (metric) to ton (US).

**How convert tonnes to m3 (tonnes to cubic meters)?**

Use the following formulas to calculate:

1) Volume = Weight / Density

2) Weight = Volume * Density

3) Density = Weight / Volume

__Example 1:__

How convert 100 tonnes water to cubic meters?

If Weight = 100 tonnes

And Density = 1000 kg/m3 (or 1 tonne/m3)

Then Volume = 100 / 1 = 100 cubic meters

__Example 2:__

How convert 2 m3 milk to tonnes?

If Volume = 2 m3

And Density = 1030 kg/m3 (or 1.03 tonne/m3)

Then Weight = 1.03 * 2 = 2.06 tonnes

__Example 3:__

How to determine air density?

If Volume = 1 m3

And Weight of this volume = 0.001225 tonnes

Then Density air = 0.001225 / 1 = 0.001225 tonne/m3

__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 = 1000 kg/m3

Density of steel = 7800 kg/m3

Density of concrete = 500 ... 2500 kg/m3

Density of sand = 1500 ... 1800 kg/m3

Density of stone = 1300 ... 3800 kg/m3

Density of garbage = 160 ... 640 kg/m3

Density of ground = 1200 ... 2000 kg/m3

Density of paint = 900 ... 1600 kg/m3

Density of air = 1.225 kg/m3

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