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.
Stone (US)
A less common US definition of the stone, about 5.67 kilograms.
A variant stone weight used in some historical US trade.
Rare; appears mainly in historical or specialized contexts.
Derived from older English stone weights that varied by commodity.
