How to convert watt-hours to electronvolts
One watt-hour equals 2.246943 × 10²² electronvolts, so multiply the number of watt-hours by 2.246943 × 10²².
eV = Wh × 2.246943 × 10²²
1 Wh = 2.246943 × 10²² eV · 1 eV = 4.450491 × 10⁻²³ Wh
Worked example
To convert 5 watt-hours to electronvolts: 5 Wh × 2.246943 × 10²² = 1.123472 × 10²³ eV.
