## Conversion Formula

By using the online converter calculator on this page, you can calculate how many atmospheres (standard) are in 'X' inches of water (X is the number of inches of water you want to convert to atmospheres (standard)). In order to convert a value from inches of water to atmospheres (standard) (from inH2O to atm) simply type the number of inches of water to be converted to atmospheres (standard) and then click on the 'convert' button. The formula used for converting a specific value from inches of water to atmospheres (standard) is:

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

where

X = the specific value to be converted (in inches of water)

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

Y = the result (in atmospheres (standard))

*Example*

Let's suppose that you have a value of pressure of 510 inches of water and want to express it in atmospheres (standard).

510 inH2O = (510 × 0.0024582482112016) atm

510 inH2O = 1.2537065877128 atm

## Conversion factor

1 inch of water is equal to 0.0024582482112016 atmosphere (standard)

(1 inH2O = 0.0024582482112016 atm )
