The electron mass 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 and can be calculated from other physical constants or measured in various ways.

30 Αυγ 2010 · Learn the difference between electron mass and electron relative atomic mass, and how they are measured. Find the CODATA recommended values for both units in kilograms and dimensionless ratios.
The rest mass of the electron, m e, is 9.109 x 10 -31 kg. If an electron is accelerated to a significant fraction of the velocity of light (as happens for example in an electron microscope) its mass increases relativistically according to the equation:
The electron has mass m_e = 9.1095\times 10^{-28}{\rm\ g}=9.1095\times 10^{-31}{\rm\ kg} = 0.51100 {\rm\ MeV}/c^2, where c is the speed of light. See also: Electron, Electron Charge
