How to use it

  1. Type the value

    The number you have, like 32 for 32 psi.

  2. Pick its unit

    Pa, hPa, kPa, MPa, mbar, bar, psi, inHg, atm, mmHg or kgf/cm².

  3. Read or copy

    Every other unit follows. Tap copy beside the one you need.

Tips

  • Tyres

    Tyre gauges read psi, bar or kPa: 2.2 bar is about 32 psi.

  • Weather

    Barometers read hPa or millibars, which are the same, or inches of mercury.

  • Hydraulics

    Hydraulic systems often run in bar or MPa: 1 MPa is 10 bar.
