Bar is a pressure unit and is about equal to the atmospheric pressure at sea level. 1 bar = 14.5037738 psi.
Bar to atm formula: 1 bar = 0.986923 atm
Pressure is measured in a variety of units all throughout the world. The units for measuring pressure are bar and atm. One newton of force applied on a 1m2 area equals one pascal. It (atm) is a unit of measurement for atmospheric pressure. In order to solve the problem, the relationship between bar and atm is useful.
