In particle physics, the electron mass (symbol: me) is the mass of a stationary electron, also known as the invariant mass of the electron. It is one of the fundamental constants of physics. It has a value of about 9.109×10 kilograms or about 5.486×10 daltons, which has an energy-equivalent of about 8.187×10 joules or about 0.5110 MeV.
