**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.

**Pascal** (abbreviations: **Pa, or N/m2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one newton per square meter. It is named after the French polymath Blaise Pascal.

## How to Convert Pounds Per Square Feet to Pascals

*Example: How many pascals are equivalent to 51.98 pounds per square feet?*

As;

1 pounds per square feet = 47.8803 pascals

51.98 pounds per square feet = Y pascals

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

Y equals 51.98 times 47.8803 over 1

(i.e.) Y = 51.98 * 47.8803 / 1 = 2488.817994 pascals

Answer is: 2488.817994 pascals are equivalent to 51.98 pounds per square feet.
