What is electron mass?

The electron rest mass is defined as the mass of a stationary electron. The electron rest mass is equal to about 9.109382 × 10-31 kilograms (1 me = 9.109382 × 10-31 kg), the base unit of mass in the International System of Units (SI). It is also equal to about 5.485799 × 10-4 atomic mass units (u).

The electron rest mass is equivalent to an energy of 0.510998910(13) megaelectronvolts (MeV) or about 8.18710438(41) × 10-14 joules (J).

The electron rest mass is used in physics and chemistry.
