Kilowatt-hours to electronvolts converter
Electronvolts (eV)
1 kilowatt-hour = 2.246943e+25 electronvolts
How to convert kilowatt-hours to electronvolts
eV = kWh × 2.24694326681 × 10^25
Multiply the number of kilowatt-hours by 2.24694326681 × 10^25 to get electronvolts. Going the other way, divide by 2.24694326681 × 10^25 (or multiply by 4.45049065 × 10^-26).
One kilowatt-hour is exactly defined as 2.24694326681 × 10^25 electronvolts (to 12 significant figures), and one electronvolt is 4.45049065 × 10^-26 kilowatt-hours.
