About these units
Kilopound (kip)
A kilopound, or kip, equals 1,000 pounds and is used primarily in structural engineering, especially in the United States. Loads, tensions, and compression forces in steel beams, concrete structures, and bridges are often expressed in kips. The kip allows engineers to avoid large numbers when expressing forces such as building loads or material stresses. In structural analysis software and construction documents, kips are ubiquitous. Despite not being a mass unit strictly speaking (it is often used as a force unit, kip-force), it remains central to American engineering practice.
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.
