Electron Rest Mass

The electron rest mass (me) is the mass of a stationary electron, equal to approximately 9.1094 × 10⁻³¹ kilograms or 0.51100 MeV/c². It is one of the fundamental physical constants and serves as the base unit of mass in atomic physics. The electron rest mass defines the scale of atomic and molecular energies and is used in quantum mechanics, particle physics, and relativistic calculations. 


Kilogram

The kilogram (also kilogramme) is the base unit of mass in the metric system, formally the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering, and commerce worldwide, and is often simply called a kilo in everyday speech.
