Units explained
Metric Ton
The metric ton (t) equals exactly 1,000 kilograms; it is also called the tonne.
From 'tun', a large medieval cask; 'metric' distinguishes it from imperial tons.
The global standard for trade, freight, and heavy industry.
Recognized internationally with the spread of the metric system in the late 19th century.
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.

Worked examples
Example 1 — Convert 1 t to AT:
1 × 34285.7103673474 = 34285.7103673474 AT
Example 2 — Convert 100 t to AT:
100 × 34285.7103673474 = 3428571.0367347389 AT
Real-world example — Geographic to architectural scale
One metric ton equals 100,000 tons (assay) (us). Map scales use this when an architectural site plan (in the smaller unit) must be related to road-network plans (in the larger unit) on the same drawing.
1 t × 34285.7103673474 = 34285.7103673474 AT
Real-world example — Geographic to architectural conversion
One metric ton equals 100,000 tons (assay) (us). The conversion bridges geographic-scale survey work and architectural-scale building plans on the same drawing.
1 t × 34285.7103673474 = 34285.7103673474 AT
