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