Millibar to Atmosphere Pressure Converter

How to convert Millibar to Atmosphere

1 mbar = 100 Pa

1 atm = 101,325 Pa

1 millibar (mbar) is equal to 0.0009869233 atmosphere (atm).

atm = mbar × 0.0009869233

Multiply the pressure in millibars by 0.0009869233:

Example: Convert 1013.25 mbar to atm:

atm = 1013.25 × 0.0009869233 = 1 atm

Millibar:		mbar
	⇅ Swap
Atmosphere:		atm
