How to use this calculator
- Enter the force (N) and the area (m²).
- Read the pressure in Pa, kPa and psi.
How it works
Pressure = force ÷ area (P = F/A). Spreading the same force over more area lowers the pressure.
Worked example
1000 N over 0.5 m². = 2000 Pa (2 kPa).
Common mistakes
- Mixing units — use newtons and square metres for pascals.
- Confusing force (N) with mass (kg) — multiply mass by g first.
Frequently asked questions
How do I get force from a weight in kg?
Multiply the mass by gravity (~9.81 m/s²) to get force in newtons, then divide by area.
