Bar is a metric unit of pressure measurement that is equal to 100,000 pascals (100 kPa). One bar is slightly less than one atmosphere.

1 bar = 0.987 atm

Other units that are derived from the bar include:

Megabar = 1,000,000 bar

Kilobar = 1,000 bar

Decibar = 0.1 bar

Centibar = 0.01 bar

Bar x 14.504 = PSI
