Convert Megaelectronvolt to Kilojoule
1 megaelectronvolt = 1.6022e-16 kilojoule (kJ). For example, 10 megaelectronvolt = 1.6022e-15 kilojoule and 100 megaelectronvolt = 1.6022e-14 kilojoule. Type any value below to convert megaelectronvolt to kilojoule both ways — it runs entirely in your browser.
Megaelectronvolt to Kilojoule conversion formula
To convert megaelectronvolt to kilojoule, multiply by 1.6022e-16:
kilojoule = megaelectronvolt × 1.6022e-16
Going the other way, 1 kilojoule = 6.2415e+15 megaelectronvolt, so
megaelectronvolt = kilojoule × 6.2415e+15.

About megaelectronvolt and kilojoule
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.
Kilojoule: A kilojoule is 1,000 joules — the energy unit on food labels (shown next to kilocalories) and for everyday amounts of energy.
Frequently asked questions
