Pressure Converter by TheCalcTools

How the Pressure Converter works

Enter the pressure and pick its unit.

Results are computed through kilopascals.

Check whether your gauge reads absolute or gauge pressure; this tool does not add atmospheric pressure.

The formula

result = value × (factor of the ‘from’ unit ÷ factor of the ‘to’ unit)1 atm = 101.325 kPa, 1 bar = 100 kPa, 1 psi ≈ 6.894757 kPa

Worked example

Using the default values shown in the calculator:

Value32
FromPSI
  1. 32 PSI equals 220632.23 Pascals ; 220.6322 Kilopascals ; 2.2063 Bar.
