About these units
Decigram (dg)
A decigram equals 1/10 of a gram and appears in older scientific literature, pharmaceutical compounding, and some food chemistry applications. Today, milligrams and grams are more common, but decigrams still offer practical value when describing masses that naturally fall between these scales, such as certain supplements or cosmetic ingredients. The decigram remains a reminder of the metric system's logical progression, offering users a consistent, scalable set of 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.
