Pressure Calculator

Calculate pressure with P = F / A. Solve for pressure, force, or area, with pressure shown in pascals, psi, and bar.

Frequently Asked Questions

What is the pressure formula?

Pressure is force divided by area: P = F / A, where force is in newtons and area in square metres. The SI unit of pressure is the pascal (Pa), equal to one newton per square metre.

How do I calculate pressure?

Divide the force by the area it acts on. For example, 500 N spread over 0.1 mΒ² gives 500 / 0.1 = 5,000 Pa (5 kPa).

How do I convert pascals to psi or bar?

1 psi = 6,894.757 Pa and 1 bar = 100,000 Pa. So 5,000 Pa β‰ˆ 0.725 psi β‰ˆ 0.05 bar. This calculator shows all three units automatically.

How do I find force from pressure and area?

Rearrange to F = P Γ— A. Multiply the pressure by the area.

How do I find area from pressure and force?

Rearrange to A = F / P. Divide the force by the pressure.
