> The pressure calculator divides a force by the area it acts on, P = F ÷ A, and shows the result in pascals, kilopascals, bar, psi and atmospheres.

## Inputs

- Force (N, kN, lbf, kgf)
- Area (m², ft², cm², in², yd², acre, ha)

## Results

- Pressure

## Formula

```
P = F ÷ A
```

## Explanation

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.

### Example values

How the main result changes when **Area** changes and everything else stays at the example values above:

## Worked example

Inputs — Force: 500 N; Area: 0.01 m².

Results — **Pressure = 50,000 Pa**.

## FAQ

**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.
