About this calculator
This converter moves between the units pressure is commonly reported in: pascal (Pa), the SI base unit; bar, close to standard atmospheric pressure; psi (pounds per square inch), standard in the US; and atmospheres (atm), defined as exactly 101,325 Pa. Each conversion uses these fixed physical constants rather than approximations.
It's used by scuba divers checking tank fill pressure in bar versus psi, mechanics reading tire pressure specs that differ by region, HVAC and process engineers converting between metric and imperial gauge readings, and students working through physics or chemistry problems that mix unit systems.
