PSI to Force Formula
The following equation is used to calculate the force from PSI.
F = PSI * A
- Where F is the force (lb-f)
- PSI is the pressure (lbs/in^2)
- A is the total surface area the pressure is acting on (in^2)
To calculate force from PSI, simply multiply the pounds per square inch by the area in inches squared.

Can you calculate Force From PSI?
PSI is a unit of pressure that measures the force per unit area, so to convert this into force, simply multiply it by the total area.
How to Calculate PSI to Force?
Example Problem:
The following example outlines the steps and information needed to calculate force from psi.
First, determine the total pressure. In this example problem, the pressure is calculated to be 200 psi.
Next, determine the total area that this pressure is acting on. In this case, the area is calculated to be 5 square inches.
Finally, calculate the Force from PSI using the formula above:
F = PSI * A
F = 200 * 5
F =1,000 lb-f
