Convert pressure between SI, imperial and engineering units, from pascals and bar to psi, atmospheres, torr and mmHg. Use it for tyre pressure, hydraulics, HVAC, weather, blood pressure and vacuum work.
Pressure is force per area. If you need the force or the area separately, try the force converter or the area converter.
Convert tyre pressures between psi, bar and kPa when specs are printed in a different unit.
Read barometric pressure in hPa (millibar), inHg or mmHg.
Match gauge readings and equipment ratings in MPa, bar and psi; blood pressure is still given in mmHg.
Conversions do not change whether a reading is gauge (relative to atmosphere) or absolute. Add about 101.325 kPa to a gauge value to get absolute pressure at sea level.
1 atm = 101,325 Pa = 1.01325 bar = 14.6959 psi = 760 mmHg (or torr).
One bar equals about 14.5038 psi. To convert bar to psi, multiply by 14.5038.
They are almost identical: 1 torr is exactly 1/760 of a standard atmosphere (133.3224 Pa), while 1 mmHg is 133.322387 Pa. The difference is negligible in practice.
A standard atmosphere is exactly 101,325 pascals.
Multiply kilopascals by 0.145038. For example, 220 kPa is about 31.9 psi.
