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.

Megapascal (abbreviations: Mpa, or MN/m2, or N/mm2): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one meganewton per square meter or one newton per square millimeter. It is named after the French polymath Blaise Pascal.

How to Convert Pounds Per Square Feet to Megapascals

Example: How many megapascals are equivalent to 71.16 pounds per square feet?


1 pounds per square feet = 4.78803E-5 megapascals

71.16 pounds per square feet = Y megapascals

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

Y equals 71.16 times 4.78803E-5 over 1

(i.e.) Y = 71.16 * 4.78803E-5 / 1 = 0.003407162148 megapascals

Answer is: 0.003407162148 megapascals are equivalent to 71.16 pounds per square feet.
