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