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.
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 Megapascals to Pounds Per Square Feet
Example: How many pounds per square feet are equivalent to 59.71 megapascals?
As;
1 megapascals = 20885.459731138 pounds per square feet
59.71 megapascals = Y pounds per square feet
Assuming Y is the answer, and by criss-cross principle;
Y equals 59.71 times 20885.459731138 over 1
(i.e.) Y = 59.71 * 20885.459731138 / 1 = 1247070.8005462 pounds per square feet
Answer is: 1247070.8005462 pounds per square feet are equivalent to 59.71 megapascals.
