**Definitions:**

**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

**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

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

*Example: How many tonnes per cubic meters are equivalent to 47 pounds per cubic feet?*

As;

1 pounds per cubic feet = 0.016018646043013 tonnes per cubic meters

47 pounds per cubic feet = Y tonnes per cubic meters

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

Y equals 47 times 0.016018646043013 over 1

(i.e.) Y = 47 * 0.016018646043013 / 1 = 0.75287636402161 tonnes per cubic meters

Answer is: 0.75287636402161 tonnes per cubic meters are equivalent to 47 pounds per cubic feet.
