How to use the pressure calculator
Compute pressure from force and area in Pa, psi and atm. Enter force, area in the fields above; the pressure, pressure, pressure, pressure are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- F — Force (N)
- A — Area (cm²)
Worked example
With force = 500 N, area = 10 cm², the calculator gives pressure ≈ 500,000 Pa; pressure ≈ 500 kPa; pressure ≈ 72.51887 psi; pressure ≈ 4.934616 atm.
Frequently asked questions
What is the formula for the pressure calculation?
Pressure (Pa) = F / (A / 10000). Pressure (kPa) = [Pressure] / 1000. Pressure (psi) = [Pressure] / 6894.757. Pressure (atm) = [Pressure] / 101325. Here F is force (N), A is area (cm²).
What inputs do I need for the pressure calculator?
You need force in N, area in cm². Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
