How to convert electronvolts to watt-hours
There are 2.246943 × 10²² electronvolts in one watt-hour, so divide the number of electronvolts by 2.246943 × 10²².
Wh = eV ÷ 2.246943 × 10²²
1 eV = 4.450491 × 10⁻²³ Wh · 1 Wh = 2.246943 × 10²² eV
Worked example
To convert 5 electronvolts to watt-hours: 5 eV ÷ 2.246943 × 10²² = 2.225245 × 10⁻²² Wh.
