What units does the converter support?

It supports Pascals (Pa), Kilopascals (kPa), Megapascals (MPa), Hectopascals (hPa), Bar, Atmospheres (atm), PSI, Torr (mmHg), Inches of Mercury (inHg), and Kilogram-force/cm² (at).

What formula is used for the calculations?

The tool uses the standard physical formula P = F/A, where pressure equals force divided by area.

What units must be used for the formula solver?

The formula solver uses standard SI units: Pascals (Pa) for pressure, Newtons (N) for force, and square meters (m²) for area.

Can I calculate the required surface area if I know the force and pressure?

Yes, select 'Area (A)' in the 'Solve For' dropdown and input the force and pressure values.

Is there a limit to the values I can convert?

No, the tool handles any positive real numbers, including small decimals and large scientific values.

Pressure Calculator & Converter (P=F/A, Pa/kPa/bar/atm/psi)

Solve pressure, force, or area from P=F/A, and convert between Pa, kPa, MPa, bar, atm, psi, Torr, inHg, kgf/cm²

Details

What this tool helps you do

Pressure is force per unit area.

Mode 1 — Formula P = F/A (three-way solver):

Pressure: P = F / A
Force: F = P · A
Area: A = F / P

Mode 2 — Unit converter across Pa, kPa, MPa, hPa, bar, atm, psi, Torr (mmHg), inHg, kgf/cm² (at).

Reference: 1 atm = 101325 Pa = 760 Torr = 14.696 psi.

100 N force on 0.5 m² area

P = 100 / 0.5 = 200 Pa = 0.2 kPa.

Convert 1 atm to all units

1 atm = 101325 Pa = 101.325 kPa = 1.01325 bar = 760 Torr = 14.696 psi.
