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.
Gram
The gram (g) equals one-thousandth of a kilogram.
From Late Latin 'gramma', a small weight or scruple.
The everyday metric unit for food, medicine, and small objects.
Defined in 1795 as the mass of one cubic centimeter of water at melting point.

100 × 29.16667 = 2916.667 g
Real-world example — Hardware-scale dimensions
A 10-ton (assay) (us) fastener or component is about as long as a thumbnail. Mechanics and DIY enthusiasts convert between tons (assay) (us) and grams daily when mixing metric and imperial tools.
10 AT × 29.16667 = 291.6667 g
Real-world example — Postcard and small-object dimensions
A postcard is about 5 tons (assay) (us) wide. Converting to grams is essential for international postal addressing forms that ask for dimensions in different units across countries.
5 AT × 29.16667 = 145.83335 g
Real-world example — Ruler-scale measurements
A 30-ton (assay) (us) school ruler converts cleanly to grams — useful when buying a desk accessory from a retailer whose product specs use a different unit.
30 AT × 29.16667 = 875.0001 g
