How to Convert Pounds Per Square Inch to Pounds Per Square Foot?

To convert a pound per square inch measurement to a pound per square foot measurement, multiply the pressure by the conversion ratio. One pound per square inch is equal to 144 pounds per square foot, so use this simple formula to convert: pounds per square foot = pounds per square inch × 144

The pressure in pounds per square foot is equal to the pounds per square inch multiplied by 144.

For Example:

How to convert 5 pounds per square inch to pounds per square foot?

Byusing the formula above

5 psi = (5 × 144) = 720 psf
