About these units
Lepton (Biblical Roman) (lepton)
The lepton, one of the smallest denominations used in Judea under Roman rule, weighed roughly 0.1–0.2 grams. It is best known from the biblical story of the Widow's Mite, representing humility and sacrificial giving. As both a coin and a mass, the lepton represents the minimal economic unit of the ancient Near East.
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.
