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