How to Convert Atmospheres to Millibars

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

Convert atmospheres to millibars with this simple formula:

millibars = atmospheres × 1,013.25

Converting an atmosphere pressure measurement to a millibar measurement involves multiplying the pressure by the conversion ratio to find the result. One atmosphere is equal to 1,013.25 millibars, so to convert simply multiply by 1,013.25.

For example, here's how to convert 5 atmospheres to millibars using the formula above.
5 atm = (5 × 1,013.25) = 5,066.25 mb
