Used mainly in precious metals and jewelry
Part of the troy weight system

Ton (Assay) (US) [AT (US)]

The assay ton (AT) is a specialized unit of weight used in the mining and precious metals industries in the United States. It is primarily used to measure ore quantities for assaying, which is the process of analyzing the metal content of ore samples.

One assay ton equals 29.1667 pounds (about 13.23 kilograms), which is different from the standard short ton (2,000 pounds). This smaller ton unit allows for more precise measurements in evaluating the value of ore deposits.

The assay ton helps miners and metallurgists accurately calculate the concentration of valuable metals like gold and silver in ores.
