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.
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.
How to Convert Pounds Per Square Feet to Tonnes Per Meters Cube
Example: How many tonnes per meters cube are equivalent to 86.5 pounds per square feet?
As;
1 pounds per square feet = 0.00478803 tonnes per meters cube
86.5 pounds per square feet = Y tonnes per meters cube
Assuming Y is the answer, and by criss-cross principle;
Y equals 86.5 times 0.00478803 over 1
(i.e.) Y = 86.5 * 0.00478803 / 1 = 0.414164595 tonnes per meters cube
Answer is: 0.414164595 tonnes per meters cube are equivalent to 86.5 pounds per square feet.
