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.

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.

How to Convert Pounds Per Square Feet to Kilopascals

Example: How many kilopascals are equivalent to 12.88 pounds per square feet?


1 pounds per square feet = 0.0478803 kilopascals

12.88 pounds per square feet = Y kilopascals

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

Y equals 12.88 times 0.0478803 over 1

(i.e.) Y = 12.88 * 0.0478803 / 1 = 0.616698264 kilopascals

Answer is: 0.616698264 kilopascals are equivalent to 12.88 pounds per square feet.
