What is a ton (assay) (us)?

The assay ton (US) equals about 29.167 grams, a mining-assay convenience unit.

Origin of the ton (assay) (us)

Devised so an assay sample's metal in milligrams reads as troy ounces per short ton.

Where it is used

Ore assaying and metallurgy.

When and where it was developed

Adopted in assay laboratories to simplify ore-grade calculation.

Hectogram to Ton (assay) (US) conversion formula

The relationship between hectograms and tons (assay) (us):
