a unit of mass used in particle physics. Mass and energy are related by Einstein's famous equation, E = mc 2. The constant c is the speed of light, 299.79 x 10 6 m/sec. An energy of 1 electronvolt is therefore equivalent to a mass of about 1.782 662 x 10-33 gram, or about 1.073 544 x 10-9 atomic mass unit.
