- 1 Wh = 2.24694326681e22 eV
- 1 × 2.24694326681e22 = 2.24694326681e22 eV
How to convert watt-hours to electronvolts
1 Wh = 2.24694326681 × 10²² eV, so multiply by 2.24694326681 to go from watt-hours to electronvolts. Going the other way, 1 eV = 4.45049065 × 10⁻²³ Wh.
eV = Wh × 2.24694326681 Wh = eV × 4.45049065
Worked example:
1 Wh = 2.24694326681e22 eV 5 × 2.24694326681e22 = 1.1234716334e23 eV
