About these units
Stone (US) (st (US))
The US stone was an informal and nonstandardized unit occasionally used in the 19th century, with no single agreed-upon value. Unlike the British stone (14 pounds), the US stone varied regionally and by trade context, typically ranging from 12 to 16 pounds, depending on the commodity and location. Farmers, butchers, and merchants sometimes used stones to weigh produce, meat, or livestock, but the lack of uniform regulation prevented it from becoming an official or widely adopted unit. Today, the US stone is entirely obsolete, but references to it appear in historical American trade documents, agricultural records, and pre-standardization weight systems. It serves as a reminder of the diversity of early American measurements before the widespread adoption of the avoirdupois pound.
Pound (Troy) (lb t)
The troy pound, equal to 12 troy ounces or 373.2417216 grams, is used almost exclusively in the precious metals trade. Unlike the avoirdupois pound used for everyday goods (16 ounces), the troy pound is optimized for precious materials such as gold, silver, and platinum. This system's origins trace back to medieval trade fairs in Troyes, France, a major commercial hub. Merchants needed a consistent unit to prevent fraud and facilitate international trading, especially for valuable metals. Today, although rarely encountered by the general public, the troy pound remains fundamental in metals pricing, refining, and numismatics. It provides continuity in a highly traditional economic sector where consistency over centuries is crucial.
