## Conversion Formula

By using the online converter calculator on this page, you can calculate how many millibars are in 'X' atmospheres (standard) (X is the number of atmospheres (standard) you want to convert to millibars). In order to convert a value from atmospheres (standard) to millibars (from atm to mbar) simply type the number of atmospheres (standard) to be converted to millibars and then click on the 'convert' button. The formula used for converting a specific value from atmospheres (standard) to millibars is:

X atmospheres (standard) * cf = Y millibars

where

X = the specific value to be converted (in atmospheres (standard))

cf = the conversion factor from atmospheres (standard) to millibars

Y = the result (in millibars)

*Example*

Let's suppose that you have a value of pressure of 631 atmospheres (standard) and want to express it in millibars.

631 atm = (631 × 1013.25) mbar

631 atm = 639360.75 mbar

## Conversion factor

1 atmosphere (standard) is equal to 1013.25 millibar

(1 atm = 1013.25 mbar )
