## PSF to PSI Formula

The formula for converting psf (pounds per square foot) to psi (pounds per square inch).

**PSI = PSF / 144 **

- PSI = Pounds per square inch
- PSF = Pounds per square foot

## How to convert psf to psi?

To convert psf to psi, divide the value in psf by 144

**Example:- Let’s say you have a value of 701.3 psf that you want to convert to psi.**

psi = psf / 144 = 701.3 / 144 = 4.8701

701.3 psf is equal to 4.8701 psi
