Units explained
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.
Poundal
The poundal (pdl) is the FPS absolute unit of force; its mass-equivalent on this scale is about 0.0141 kg.
Defined in the foot-pound-second absolute system in the late 19th century.
Early 20th-century physics and engineering.
Introduced in the absolute FPS system as an alternative to gravitational units.
