Kilojoules to kilo-electron volts converter above calculates how many kilo-electron volts are in 'X' kilojoules (where 'X' is the number of kilojoules to convert to kilo-electron volts). In order to convert a value from kilojoules to kilo-electron volts (from kJ to keV) simply type the number of kJ to be converted to keV and then click on the 'convert' button.
