Units explained
Gigagram
A gigagram (Gg) equals 10^6 kilograms, the same as 1,000 metric tons.
From the SI prefix 'giga-' (from Greek 'gigas', giant).
Bulk commodity, emissions, and freight accounting.
The giga- prefix entered the SI in 1960.
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.
