**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

**Kilonewton Per Cubic Meter** (abbreviations: **kN/m3, or kNpm3**): is an SI derived unit of density, defined by mass in kilonewton divided by volume in cubic meter

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

*Example: How many kilonewton per cubic meters are equivalent to 73.08 tonnes per cubic meters?*

As;

1 tonnes per cubic meters = 9.8066358553261 kilonewton per cubic meters

73.08 tonnes per cubic meters = Y kilonewton per cubic meters

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

Y equals 73.08 times 9.8066358553261 over 1

(i.e.) Y = 73.08 * 9.8066358553261 / 1 = 716.66894830723 kilonewton per cubic meters

Answer is: 716.66894830723 kilonewton per cubic meters are equivalent to 73.08 tonnes per cubic meters.
