**Definitions:**

**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 82.75 kilopascals?*

As;

1 kilopascals = 20.8854 pounds per square feet

82.75 kilopascals = Y pounds per square feet

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

Y equals 82.75 times 20.8854 over 1

(i.e.) Y = 82.75 * 20.8854 / 1 = 1728.26685 pounds per square feet

Answer is: 1728.26685 pounds per square feet are equivalent to 82.75 kilopascals.
