How to Convert Millibars to Atmospheres Using an Easy Conversion Formula

Calculators can be used to convert measurements from one unit to another

Convert millibars to atmospheres with this simple formula:

atmospheres = millibars × 0.000987

Converting a millibar pressure measurement to an atmosphere measurement involves multiplying your pressure by the conversion ratio to find the result. A millibar is equal to 0.000987 atmospheres, so to convert simply multiply by 0.000987.

For example:
5 mb = (5 × 0.000987) = 0.004935 atm
