The mass of the electron at rest (stationary) is called as the rest mass of the electron. (i.e.,) The mass of the electron when the speed is zero. The value of electron rest mass is 9.109 382 91[40] e^-31 kg. It is denoted by me. It is related to other physical constants like Rydberg constant, Avogadro number, atomic mass constant.
