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.
Wey
The wey was an English bulk weight, here taken as 252 pounds (about 114.3 kg).
From Old English 'waege', a weighing or balance.
Obsolete English unit for wool, cheese, and salt.
Used in medieval and early-modern English trade.
