**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

**Pound Per Cubic Foot** (abbreviations: **lb/ft3, or ppf3**): is a unit of density, defined by mass in pound divided by volume in cubic foot

## How to Convert Tonnes Per Cubic Meters to Pounds Per Cubic Feet

*Example: How many pounds per cubic feet are equivalent to 79.16 tonnes per cubic meters?*

As;

1 tonnes per cubic meters = 62.989142857143 pounds per cubic feet

79.16 tonnes per cubic meters = Y pounds per cubic feet

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

Y equals 79.16 times 62.989142857143 over 1

(i.e.) Y = 79.16 * 62.989142857143 / 1 = 4986.2205485714 pounds per cubic feet

Answer is: 4986.2205485714 pounds per cubic feet are equivalent to 79.16 tonnes per cubic meters.
