How to convert Atmosphere to Bar
Multiply the atmosphere value by 1.01325: 1 atm = 1.01325 bar. Going the other way, 1 bar = 0.986923 atm, so divide by 1.01325 or use the Bar to Atmosphere converter.
About these units
Atmosphere (atm)
A standard atmosphere is defined as exactly 101,325 pascals, roughly the average air pressure at sea level. It is about 14.7 psi or 1.013 bar.
Bar (bar)
A bar is exactly 100,000 pascals, very close to average atmospheric pressure at sea level. Tyre pressures and scuba tanks are often rated in bar.
