Pressure Calculator
Enter force and area to compute pressure p = F/A.

At a glance:Pressure is the normal force distributed over an area: p = F/A (SI unit pascal = N/m²). It is a scalar (force per area, not direction). A given force concentrated on a small area produces high pressure (e.g. a knife edge, high heels) while spread over a large area gives low pressure (snowshoes, tank treads). For fluids at rest, pressure increases with depth (hydrostatic) and is transmitted equally (Pascal). This tool computes p = F/A from force and area, reporting Pa and common multiples.
Formula
p = F/A
1 Pa = 1 N/m², 1 atm ≈ 101325 Pa
$$P = \frac{F}{A}$$How to Use
- Enter the force F (N).
- Enter the area A (m²).
- The calculator returns the pressure p.
Case Studies
Standing on one foot
F = 700 N, A = 0.02 m² (one foot).
p = 700/0.02 = 35000 Pa.
Standing on both feet (0.04 m²): 17500 Pa.
FAQ
Why does a sharp object cut more easily?
The same force over a tiny area gives very high pressure, exceeding the material's strength — that's why a knife edge or nail concentrates force.
Is pressure a vector?
No, pressure is a scalar (force per area). The force it produces acts normal to a surface.
