Units explained
Ton (assay) (UK)
The assay ton (UK) equals about 32.667 grams, the long-ton analog of the assay ton.
The long-ton version of the assay-ton convenience unit.
Ore assaying in long-ton (imperial) contexts.
Adopted in assay laboratories using the long ton.
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) (UK) to Metric Ton conversion formula
The relationship between tons (assay) (uk) and metric tons:
To convert tons (assay) (uk) to metric tons, multiply the value in tons (assay) (uk) by 3.266667e-5. To reverse, multiply metric tons by 30612.2448667222.

Step-by-step: convert tons (assay) (uk) to metric tons
- Write down the value in tons (assay) (uk) (AT).
- Multiply that value by the factor 3.266667e-5.
- The product is the equivalent value in metric tons (t).
- To reverse, multiply the metric ton value by 30612.2448667222.
Worked examples
Example 1 — Convert 1 AT to t:
1 × 3.266667e-5 = 3.266667e-5 t
Example 2 — Convert 100 AT to t:
100 × 3.266667e-5 = 0.0032666667 t
Real-world example — Small to geographic-scale
100,000 tons (assay) (uk) equals one metric ton — a useful conversion when small-scale survey diagrams must be related to road-network distances on a different map.
100000 AT × 3.266667e-5 = 3.26666667 t
Real-world example — Architectural to geographic scale
A 100,000-ton (assay) (uk) measurement equals one metric ton. The five-order-of-magnitude scale change comes up in mapping work where architectural site plans must be related to road-network maps.
100000 AT × 3.266667e-5 = 3.26666667 t
