The Pressure Converter changes any pressure value between scientific, engineering and everyday units. Enter a value, choose your units, and get an accurate result plus a table covering metric and imperial pressure units.
Every pressure unit covered
This converter supports pascals, hectopascals, kilopascals and megapascals, plus bar, millibar, atmospheres, torr (mmHg), psi and inches of mercury. That range covers weather, tire pressure, hydraulics, vacuum systems and lab work.
Conversions are based on standard definitions (1 atm = 101,325 Pa, 1 psi = 6894.757 Pa), so results are precise to scientific standards.
Common pressure conversions
- psi to bar and bar to psi for tires
- kPa to psi for engineering
- mmHg to kPa for blood pressure and vacuum
