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