megaelectron volt
Energyexact by definition
The megaelectronvolt is exactly 10⁶ electronvolts, or 1.602176634 × 10⁻¹³ joules, exact since the 2019 fixing of the elementary charge. It is the natural scale of nuclear physics: nuclear binding energies are around 8 MeV per nucleon, and an electron's rest mass is 0.511 MeV/c².
