Convert between 8 pressure units.
About Pressure
Pressure is force spread over an area. The SI unit is the pascal, but it's a small quantity, so real figures use multiples: standard atmospheric pressure is 101,325 Pa, or 1,013.25 hPa — the hectopascals in weather reports. Tyres are quoted in bar or psi, where 1 bar is 14.504 psi, so a 2.2 bar tyre is about 32 psi.
