Enter a pressure in any one unit and see the same pressure converted into Pa, kPa, MPa, bar, mbar, psi, atm, Torr, mmHg and inHg.
Every result is converted through pascals, the SI unit of pressure: the entered value is first multiplied by its unit factor to get pascals, then divided by each target unit factor. One bar is exactly 100,000 Pa, one standard atmosphere is 101,325 Pa, and one psi is about 6,894.76 Pa. The same table serves tyre-pressure conversions, since tyre pressures are commonly quoted in psi, bar and kPa — a typical car tyre figure in one unit can be read off in the others directly.
How is tyre pressure converted between psi, bar and kPa? Enter the tyre pressure in whichever unit is known and read the other units from the table. As a guide, 32 psi is about 2.21 bar and about 221 kPa.
Are Torr and mmHg the same? For practical purposes, yes. One Torr and one millimetre of mercury differ by less than one part in ten million, so both use essentially the same factor here: about 133.322 Pa.
