Convert Kilowatt-hour to Megaelectronvolt
1 kilowatt-hour = 2.2469e+19 megaelectronvolt (MeV). For example, 10 kilowatt-hour = 2.2469e+20 megaelectronvolt and 100 kilowatt-hour = 2.2469e+21 megaelectronvolt. Type any value below to convert kilowatt-hour to megaelectronvolt both ways — it runs entirely in your browser.
Kilowatt-hour to Megaelectronvolt conversion formula
To convert kilowatt-hour to megaelectronvolt, multiply by 2.2469e+19:
megaelectronvolt = kilowatt-hour × 2.2469e+19
Going the other way, 1 megaelectronvolt = 4.4505e-20 kilowatt-hour, so
kilowatt-hour = megaelectronvolt × 4.4505e-20.

About kilowatt-hour and megaelectronvolt
Kilowatt-hour: A kilowatt-hour is 1,000 watt-hours — exactly 3,600,000 joules (3.6 MJ). It is the "unit" your electricity meter bills.
Megaelectronvolt: A megaelectronvolt is the energy an electron gains across a one-million-volt potential — 1 MeV = 1.602176634 × 10⁻¹³ J (the elementary charge is exact since the 2019 SI redefinition). Standard in nuclear and particle physics.
