How the conversion works
Multiply by 1.602176634e-22 to go from electron volt to kilojoule, 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? kilojoule to electron volt — 1 kJ = 6.241509074e+21 eV.
