The same force spread over a larger area produces lower pressure, which is why snowshoes work and knives cut.
How to use the Pressure Calculator
- Force
- Area
- Want to work backwards? Type a value into Pressure and Area is calculated for you.
Results update as you type, and every field accepts the units shown in its menu.
How it works
Divide force in newtons by area in square metres to get pascals.
Inputs explained
| Field | What to enter |
|---|---|
| Force | Units: N, kN, lbf, kgf |
| Area | Units: m², ft², cm², in², yd², acre … |
Example values
How the main result changes when Area changes and everything else stays at the example values above:
| Area (m²) | Pressure (Pa) |
|---|---|
| 0.005 | 100,000 |
| 0.0075 | 66,666.67 |
| 0.01 | 50,000 |
| 0.0125 | 40,000 |
| 0.015 | 33,333.33 |
| 0.02 | 25,000 |
Formula
P = F ÷ AWorked example
Inputs — Force: 500 N; Area: 0.01 m².
Results — Pressure = 50,000 Pa.
Frequently asked questions
What is atmospheric pressure?
About 101,325 Pa or 14.7 psi at sea level.
Is pressure a vector?
No, it acts equally in all directions in a fluid.
What formula does the Pressure Calculator use?
P = F ÷ A.
Can I work backwards from the result?
Yes. Type the result you want into Pressure and the calculator finds the matching area.
