The rest mass of an electron is the intrinsic mass of an electron when it is at rest (not moving relative to an observer).

Its value is approximately 9.109 × 10⁻³¹ kilograms (or about 0.511 MeV/c² in energy units).

This tiny mass is fundamental to atomic and particle physics, influencing how electrons behave in atoms and electric currents.

Summary:

Kilogram (kg)

The kilogram is the SI base unit of mass, representing the amount of matter in an object.

It is symbolized as kg.
Since 2019, the kilogram is defined by fixing the value of the Planck constant to exactly $6.62607015 \times 10^{-34}$ joule seconds, linking mass to fundamental physical constants.
Before this, it was defined by a physical platinum-iridium prototype.
It is the only SI base unit still using the prefix "kilo" in its name.

Key points:

The kilogram ensures accurate and universal mass measurements across the world.
