Calculation Formula

PSF = PSI × 144

Where:
PSI = Pounds per square inch
PSF = Pounds per square foot
144 = Number of square inches in a square foot

How to Use the Calculator

  1. Enter the pressure value in PSI (pounds per square inch) in the input field.
  2. Click the "Calculate" button to convert the PSI value to PSF (pounds per square foot).
  3. The converted value in PSF will be displayed in the result field.
  4. Use the "Reset" button to clear the input and result fields.

Understanding PSI and PSF

PSI (pounds per square inch) is a unit of pressure that measures the amount of force applied per unit area. PSF (pounds per square foot) is another unit of pressure that measures the amount of force applied per unit area, but on a larger scale (one square foot instead of one square inch).

The conversion from PSI to PSF is done by multiplying the PSI value by 144, since there are 144 square inches in one square foot.

Example

If you have a pressure of 50 PSI, the conversion to PSF would be:

50 PSI × 144 = 7200 PSF
