Why does the US assay ton have variable mass?

The US assay ton is a historic mining unit whose exact mass has differed depending on location and period, so modern reports specify explicit mass units to avoid confusion.

What is the difference between avoirdupois and troy ounces?

The avoirdupois ounce is commonly 28.349523125 grams, mainly for general purposes, while the troy ounce is 31.1034768 grams, used for precious metals.

When should this conversion be used?

Use this conversion when reporting or comparing precious metal content, settling contracts for ore, or interpreting historic assay data.
