**Definitions:**

**Tonne Per Meter Cube** (abbreviations: **t/m2, or tpm2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength interms of tonne per meter cube.

**Pound Per Square Foot** (abbreviations: **psf, or lb/ft2**): is a British (Imperial) and American pressure unit which is directly related to the psi pressure unit by a factor of 144 (1 sq ft = 12 in x 12 in = 144 sq in). Where, 1 pound per square foot equals 47.8803 pascals.

## How to Convert Tonnes Per Meters Cube to Pounds Per Square Feet

*Example: How many pounds per square feet are equivalent to 42.29 tonnes per meters cube?*

As;

1 tonnes per meters cube = 208.854 pounds per square feet

42.29 tonnes per meters cube = Y pounds per square feet

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

Y equals 42.29 times 208.854 over 1

(i.e.) Y = 42.29 * 208.854 / 1 = 8832.43566 pounds per square feet

Answer is: 8832.43566 pounds per square feet are equivalent to 42.29 tonnes per meters cube.
