**Definitions:**

**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 36.73 pounds per square feet?*

As;

1 pounds per square feet = 0.0478803 kilopascals

36.73 pounds per square feet = Y kilopascals

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

Y equals 36.73 times 0.0478803 over 1

(i.e.) Y = 36.73 * 0.0478803 / 1 = 1.758643419 kilopascals

Answer is: 1.758643419 kilopascals are equivalent to 36.73 pounds per square feet.
