How the conversion works
Multiply by 1.602176634e-19 to go from electron volt to joule, 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? joule to electron volt — 1 J = 6.241509074e+18 eV.
