About these units
Ton (Assay) (US) (AT (US))
The US assay ton is a specialized unit used in mining and metallurgy for evaluating ore grades. It is defined as 29.166⅔ grams, a very small mass chosen to simplify calculations relating assay results to tons of ore. The idea is that if an assay ton of sample yields 1 milligram of precious metal, then one actual ton of ore contains 1 ounce of that metal. This scaling makes laboratory results directly translatable to mining yields. While obsolete in modern industrial practice, where metric units dominate, the assay ton remains important in historical mining records and for researchers studying early industrial metallurgy.
Tetradrachma (Biblical Greek) (tetradrachma)
A tetradrachma weighed about 17 grams, equivalent to four drachmas. It became one of the most widely circulated silver coins in the ancient world, especially under the Athenian empire. Athenian tetradrachms, often stamped with the iconic owl design, were standardized, highly trusted, and circulated across the Mediterranean as an international currency. Although now primarily of numismatic interest, tetradrachms are key archaeological artifacts, illuminating trade networks, political authority, and artistic expression.
