How to Calculate Pressure

Pressure is a measure of how much force is applied over a given area. Pressure is typically measured in pascals (Pa) in the International System of Units (SI), where one pascal is equal to one newton of force acting on one square meter of area.

You can calculate pressure if you know the amount of force applied over the area using a formula.

Pressure Formula

The pressure formula states:

P = F / A

Thus, the pressure P in pascals is equal to the force F in newtons applied divided by the area A in square meters.

How to Calculate Force

If you know the pressure and the area, rearrange the pressure formula to solve for force.

F = PA

The force is equal to the pressure P times the area A.

How to Calculate Area

If you know the pressure and the applied force, rearrange the pressure formula to solve for area.

A = F / P

Thus, the area A in square meters is equal to the force F in newtons divided by the pressure P in pascals.
