Kilopascal (abbreviations: kPa, or kN/m2): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one kilonewton per square meter. 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 Kilopascals to Pounds Per Square Feet

Example: How many pounds per square feet are equivalent to 1.33 kilopascals?


1 kilopascals = 20.8854 pounds per square feet

1.33 kilopascals = Y pounds per square feet

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

Y equals 1.33 times 20.8854 over 1

(i.e.) Y = 1.33 * 20.8854 / 1 = 27.777582 pounds per square feet

Answer is: 27.777582 pounds per square feet are equivalent to 1.33 kilopascals.
