**Pound Per Cubic Inch** (abbreviations: **lb/in3, or ppi3**): is a unit of density, defined by mass in pound divided by volume in cubic inch

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

*Example: How many pounds per cubic inches are equivalent to 30.9 tonnes per cubic meters?*

As;

1 tonnes per cubic meters = 0.036127097535396 pounds per cubic inches

30.9 tonnes per cubic meters = Y pounds per cubic inches

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

Y equals 30.9 times 0.036127097535396 over 1

(i.e.) Y = 30.9 * 0.036127097535396 / 1 = 1.1163273138437 pounds per cubic inches

Answer is: 1.1163273138437 pounds per cubic inches are equivalent to 30.9 tonnes per cubic meters.
