Kilojoules to liter-atmosphere conversion calculator shown above calculates how many liter-atmosphere are in 'X' kilojoules (where 'X' is the number of kilojoules to convert to liter-atmosphere). In order to convert a value from kilojoules to liter-atmosphere (from kJ to L atm) just type the number of kJ to be converted to L atm and then click on the 'convert' button.
