## Conversion Formula

By using the online converter calculator on this page, you can calculate how many millimeters of water are in 'X' atmospheres (standard) (X is the number of atmospheres (standard) you want to convert to millimeters of water). In order to convert a value from atmospheres (standard) to millimeters of water (from atm to mmH2O) simply type the number of atmospheres (standard) to be converted to millimeters of water and then click on the 'convert' button. The formula used for converting a specific value from atmospheres (standard) to millimeters of water is:

X atmospheres (standard) * cf = Y millimeters of water

where

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

cf = the conversion factor from atmospheres (standard) to millimeters of water

Y = the result (in millimeters of water)

*Example*

Let's suppose that you have a value of pressure of 42 atmospheres (standard) and want to express it in millimeters of water.

42 atm = (42 × 10332.559007503) mmH2O

42 atm = 433967.47831514 mmH2O

## Conversion factor

1 atmosphere (standard) is equal to 10332.559007503 millimeter of water

(1 atm = 10332.559007503 mmH2O )
