Electron rest mass

The electron rest mass (symbol: $m e$ ) is the mass of a stationary electron. It is one of the fundamental constants of physics, and is also very important in chemistry because of its relation to the Avogadro constant. It has a value of about 6969911000000000000♠9.11×10 kilograms or about 6996548600000000000♠5.486×10 atomic mass units, equivalent to an energy of about 6986818999999999999♠8.19×10 joules or about 0.511 megaelectronvolts.
