Atmospheric pressure (atm) to bars conversion table shows the most common values for the quick reference. Alternatively, you may use the converter to convert any other values.
1 Atm = 1.01325 Bars
Atmospheric pressure (atm) is the force per unit area by the weight of air above that point. 1 atmosphere is about 101.325 kilopascals. Barometer is a device used to measure the atmospheric pressure.
Bar is the atmospheric pressure at the sea level, which is around 100 kilopascals. Since the difference between atm and bar is so small, in most applications bar unit is used.
