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.
Dekagram
A dekagram (dag) equals 0.01 kilogram, or 10 grams.
From the SI prefix 'deka-' (from Greek 'deka', ten).
Widely used in Central and Eastern European cooking and shops (dag/dkg).
Part of the original metric system introduced in 1795.

Real-world example — Postcard and small-object dimensions
A postcard is about 5 tons (assay) (us) wide. Converting to dekagrams is essential for international postal addressing forms that ask for dimensions in different units across countries.
5 AT × 2.916667 = 14.583335 dag
Real-world example — Ruler-scale measurements
A 30-ton (assay) (us) school ruler converts cleanly to dekagrams — useful when buying a desk accessory from a retailer whose product specs use a different unit.
30 AT × 2.916667 = 87.50001 dag
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 dekagrams daily when mixing metric and imperial tools.
10 AT × 2.916667 = 29.16667 dag
