Pressure Converter

Convert between any of the 9 supported Pressure units. Pick the units, type a value, done.

Supported units

Pascals (Pa): The SI unit: one newton per square meter. Small, so kPa and MPa are more common.

Kilopascals (kPa): 1,000 Pa. Weather systems and tire pressure in metric countries.

Megapascals (MPa): One million Pa. Material strength and hydraulics.

Bar (bar): 100,000 Pa, close to one atmosphere. Tire pressure and diving in Europe.

PSI (psi): Pounds per square inch, about 6,895 Pa. Tire pressure in the US.

Atmospheres (atm): Standard sea-level air pressure: 101,325 Pa.

mmHg (mmHg): Millimeters of mercury, about 133.3 Pa. Blood pressure and vacuum work.

Inches of Mercury (inHg): About 3,386 Pa. Barometric pressure in US weather reports and aviation.

Torr (Torr): 1/760 of an atmosphere, virtually identical to the mmHg. Vacuum systems and chemistry labs.
