How to convert electronvolts to kilowatt-hours
There are 2.246943 × 10²⁵ electronvolts in one kilowatt-hour, so divide the number of electronvolts by 2.246943 × 10²⁵.
kWh = eV ÷ 2.246943 × 10²⁵
1 eV = 4.450491 × 10⁻²⁶ kWh · 1 kWh = 2.246943 × 10²⁵ eV
Worked example
To convert 5 electronvolts to kilowatt-hours: 5 eV ÷ 2.246943 × 10²⁵ = 2.225245 × 10⁻²⁵ kWh.
