1 bar (bar) = 100 kilopascal (kPa)
1 kilopascal (kPa) = 0.145 pounds force per square inch (psi²) = 0.0102 kilogram force per square centimeter (kgf/cm²) = 0.0098 atmospheric pressure (atm)
1 pound force/inch (psi) = 6.895 kPa (kPa) = 0.0703 kilogram force/cm (kg/cm) = 0.0689 bar (bar) = 0.068 atmosphere (atm)
1 physical atmosphere (atm) = 101.325 kPa (kPa) = 14.696 pounds/inch (psi) = 1.0333 bar (bar)
1 engineering atmospheric pressure = 98.0665 kilopascal (kPa)
1 millimeter of water column (mmH2O) = 9.80665 Pascal (Pa) 1 millimeter of mercury column (mmHg) = 133.322 Pascal (Pa)
1 Torr (Torr) = 133.322 Pascal (Pa) 1 dyn/cm (dyn/cm) = 0.1 Pascal (Pa)
