1 bar = 100 kilopascal (kPa)
1 kilopascal (kPa) = 0,145 pond kracht per vierkante inch (psi²) = 0,0102 kilogram kracht per vierkante centimeter (kgf/cm²) = 0,0098 atmosfeer (atm)
1 pond kracht per inch (psi) = 6,895 kilopascal (kPa) = 0,0703 kilogram kracht per centimeter (kg/cm) = 0,0689 bar = 0,068 atmosferische druk (atm)
1 fysische atmosfeer (atm) = 101,325 kilopascal (kPa) = 14,696 pounds per inch (psi) = 1,0333 bar (bar)
1 technische atmosfeer = 98,0665 kilopascal (kPa)
1 millimeter waterkolom (mmH2O) = 9,80665 Pa (Pa) 1 millimeter kwik (mmHg) = 133,322 Pa (Pa)
1 Torr = 133,322 Pa 1 dyn/cm = 0,1 Pa
