About these units
Quarter (UK) (qr (UK))
The UK quarter, equal to 28 pounds, corresponds to 1/4 of a UK hundredweight. Historically used in grain trade, wool markets, and taxation, it reflects the older English approach to structuring weights around the stone. Its direct link to the long hundredweight made it easy for merchants to calculate loads and price goods. While obsolete today, the UK quarter remains important for historians reconstructing traditional British commerce and agricultural economies.
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.
