**Definitions:**

**Tonne Per Cubic Meter** (abbreviations: **t/m3, or tpm3**): is a unit of density, defined by mass in tonnes divided by volume in cubic meter

**Kilogram Per Cubic Meter** (abbreviations: **kg/m3, or kgpm3**): is an SI derived unit of density, defined by mass in kilograms divided by volume in cubic metres.

## How to Convert Tonnes Per Cubic Meters to Kilograms Per Cubic Meters

*Example: How many kilograms per cubic meters are equivalent to 47.2 tonnes per cubic meters?*

As;

1 tonnes per cubic meters = 1000 kilograms per cubic meters

47.2 tonnes per cubic meters = Y kilograms per cubic meters

Assuming Y is the answer, and by criss-cross principle;

Y equals 47.2 times 1000 over 1

(i.e.) Y = 47.2 * 1000 / 1 = 47200 kilograms per cubic meters

Answer is: 47200 kilograms per cubic meters are equivalent to 47.2 tonnes per cubic meters.
