How the conversion works

Multiply by 6.241509074e+18 to go from joule 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 joule — 1 eV = 1.602176634e-19 J.
