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