Pressure Calculator
P = F / A • Pressure from force and area
Force may be positive or negative depending on direction.
Area must be greater than 0.

Results are calculated from SI units after converting your selected force and area units.
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.
