Units explained
Kilogram
The kilogram (kg) is the SI base unit of mass, defined by fixing the Planck constant h at 6.62607015E-34 J s.
From Greek 'khilioi' (thousand) plus 'gramma' (small weight).
The worldwide base unit of mass in science, commerce, and everyday life.
Adopted in 1795; redefined through the Planck constant on 20 May 2019.
Electron Mass (rest)
The electron rest mass is about 9.109E-31 kg.
The mass of the electron, the lightest charged elementary particle.
Atomic and particle physics.
Quantified after J. J. Thomson identified the electron in 1897.
