Units explained
Ton (assay) (US)
The assay ton (US) equals about 29.167 grams, a mining-assay convenience unit.
Devised so an assay sample's metal in milligrams reads as troy ounces per short ton.
Ore assaying and metallurgy.
Adopted in assay laboratories to simplify ore-grade calculation.
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.
