The conversion relationship between psi and bar is 1psi=0.0689475728bar.

psi is a unit of measurement. p refers to pound force, s refers to square, i refers to inch. The United States customarily uses psi as the unit, which means pound force/square inch. Convert all units to metric units and you can calculate: 1bar≈14.5psi.

Bar is a commonly used unit of pressure. Millibars were commonly used in meteorology earlier, and later the equivalent international unit hectopascals was used. The unit kilogram force is still used in engineering. 1 kilogram force is equal to 9.80665 Newtons.

It follows that: 1 kilogram force/square centimeter = 0.967841 atmospheric pressure = 98066.5 Pascal = 1 engineering atmosphere.

Millimeter of mercury is also a commonly used unit of pressure. The pressure unit defined by the pressure generated by 1 mm of mercury is Torr (Torr).

Conversion relationship

1 standard atmospheric pressure (atm) = 14.696 pounds/inch2 (psi)

1 bar (bar) = 100 kilopascal (kPa)

1 dyn/cm2 (dyn/cm2) = 0.1 Pa (Pa)

1 Torr (Torr) = 133.322 Pa (Pa)

1 Millimeters of mercury (mmHg) = 133.322 Pascals (Pa)

1 millimeter of water column (mmH2O) = 9.80665 Pascals (Pa)

1 Engineering atmospheric pressure = 98.0665 kilopascals (kPa)

1 kPa (kPa) = 0.145 lbf/in2 (psi) = 0.0102 kilogram force/cm2 (kgf/cm2) = 0.0098 atmospheric pressure (atm)

1 lbf/ Inch2 (psi) = 6.895 kilopascal (kPa) = 0.0703 kilogram force/cm2 (kgf/cm2) = 0.0689 bar (bar) = 0.068 atmospheric pressure (atm)

1 standard atmospheric pressure (atm) = 101.325 kPa (kPa) = 14.696 pounds/inch2 (psi) = 1.0133 bar (bar) = 760 millimeters of mercury (mmHg)
