Kilopascals (kPa), pounds per square inch (psi), bar, atmosphere (atm), Torr (mmHg), and millibar (mbar). All conversions are bidirectional.
kPa: SI standard, meteorology. psi: tire pressure, US hydraulics. bar: industrial, European. atm: chemistry. Torr: vacuum systems. mbar: weather.
1 atm = 101.325 kPa = 14.696 psi = 1.01325 bar = 760 Torr = 1013.25 mbar. These are exact SI definitions.
The converter uses absolute pressure by default. For gauge pressure, add atmospheric pressure (101.325 kPa) before converting.
