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.
Ton (assay) (UK)
The assay ton (UK) equals about 32.667 grams, the long-ton analog of the assay ton.
The long-ton version of the assay-ton convenience unit.
Ore assaying in long-ton (imperial) contexts.
Adopted in assay laboratories using the long ton.
