How to convert Millibar to Atmosphere
Multiply the millibar value by 0.000986923: 1 mbar = 0.000986923 atm. Going the other way, 1 atm = 1,013.25 mbar, so divide by 0.000986923 or use the Atmosphere to Millibar converter.
About these units
Millibar (mbar)
A millibar is one thousandth of a bar, exactly 100 pascals (1 hPa). It is the traditional unit on weather maps.
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.
