Physics Pressure: Force Spread Over Area
The same force feels very different spread over a pin or a plank. Pressure captures that spread in one division.
What is the Physics Pressure Calculator?
Enter force in newtons and area in square metres. Pressure in pascals is force divided by area. All physics tools here use standard textbook formulas, labelled as such.
How to use it
- Enter the values in the labelled units.
- Click Calculate Pressure.
- Read the result and its formula.
Worked example
A force of 100 N over 2 m^2 gives a pressure of 50 Pa.
What pressure is 100 N over 2 square metres?
50 pascals, from 100 divided by 2.
Frequently asked questions
What units should I use?
Use the units on the labels (kg, m, s, N, J, W) so the formula's result comes out in standard units.
Is this exact?
The formula is standard textbook physics; real measurements carry their own errors, but the arithmetic is exact.
