About the Pressure calculator

Convert pressure between pascals, bar, PSI and atmospheres.

How to use the Pressure calculator

  1. Enter the Pressure Value and choose the Input Unit.
  2. Press Calculate to see all the equivalent values.

Formula and method

1 atm = 101,325 Pa = 1.01325 bar = 14.696 PSI. 1 bar = 100,000 Pa.

Worked example

A car tyre at 32 PSI is about 2.2 bar or 220.6 kPa.

Tips

  • Gauge pressure ignores atmospheric pressure, absolute pressure includes it.

Frequently asked questions

What is the recommended tyre pressure?
Check the sticker in your car's door frame or manual, not the tyre sidewall.
