Pressure

Pressure is a measurement of the force a gas exerts on a given area. It is most commonly measured in pounds per square inch (psi) bar, kg/cm² or atmospheres. The latter three units are quite similiar and can often be used together without conversion.

Conversion factors (rounded to 3 decimal places):

1 bar	= 14.504 psi	= 1.02 kg/cm2	= 0.987 atm
1 psi	= 0.069 bar	= 0.07 kg/cm2	= 0.068 atm
1 kg/cm2	= 0.98 bar	= 14.223 psi	= 0.968 atm
1 atm	= 1.013 bar	= 14.696 psi	= 1.033 kg/cm2
