How the conversion works
Multiply by 4.450490650e-23 to go from electron volt to watt-hour, 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? watt-hour to electron volt — 1 Wh = 2.246943267e+22 eV.
