About these units
Drachma (Biblical Greek) (drachma)
The drachma, roughly 4.3 grams, served as the principal Greek silver unit for centuries. Both a mass and a monetary unit, the drachma appears extensively in ancient writings, from philosophy to commerce to biblical passages. The term originates from "a handful," linking the weight to early barter practices. Over time, it became a symbol of civic identity—different city-states minted distinct drachmas with unique iconography. Its influence survives in the name of Greece's former national currency, the drachma, reinforcing its cultural legacy.
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.
