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