Use this Pressure Calculator to calculate pressure from force and the area over which that force acts.

Calculation Method

Pressure = Force ÷ Area

P = F ÷ A

When force is measured in newtons and area in square meters, pressure is measured in pascals:

1 Pa = 1 N/m²

Example

If a force of 500 N acts over an area of 0.25 m²:

P = 500 ÷ 0.25

P = 2,000 Pa

Important Note

The formula uses the force acting perpendicular to the surface. This calculator does not directly calculate hydrostatic pressure from fluid density and depth.
