How the Pressure Calculator works
Enter the force and the area it acts on.
Pressure is force divided by area, in pascals when using newtons and square metres.
The calculator converts to other common pressure units.
The formula
P = F ÷ A1 atm = 101,325 Pa
Worked example
Using the default values shown in the calculator:
| Force (N) | 500 |
|---|---|
| Area (cm²) | 25 |
- Area = 25 cm² = 0.0025 m².
- P = 500 ÷ 0.0025 = 200,000 Pa = 200 kPa.
- In psi that is 29.01.
Result:
| Pressure (Pa) | 200,000 |
|---|---|
| Pressure (kPa) | 200.00 |
| Pressure (bar) | 2.0000 |
| Pressure (psi) | 29.008 |
| Pressure (atm) | 1.9738 |
Frequently asked questions
Why does a sharp knife cut better?
The same force on a smaller area gives a much higher pressure.
What is atmospheric pressure?
About 101,325 Pa at sea level, which is also 1.013 bar or 14.7 psi.
