Millijoules to liter-atmosphere converter above calculates how many liter-atmosphere are in 'X' millijoules (where 'X' is the number of millijoules to convert to liter-atmosphere). In order to convert a value from millijoules to liter-atmosphere (from mJ to L atm) just type the number of mJ to be converted to L atm and then click on the 'convert' button.
