How the conversion works
Multiply by 6.241509074e+21 to go from kilojoule to electron volt, or divide by it to go back. Every conversion on this site routes through the SI value (J) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? electron volt to kilojoule — 1 eV = 1.602176634e-22 kJ.
