The stone (st) is a British imperial unit of mass equal to exactly 14 avoirdupois pounds or 6.35029318 kilograms. Used almost exclusively in the United Kingdom and Ireland for human body weight, it has no role in scientific, commercial, or international contexts. The stone is not an SI unit and was removed from official UK trade measurement in 1985, though it remains deeply embedded in everyday British culture.
The US short ton (commonly just "ton" in American usage) equals exactly 2,000 avoirdupois pounds or approximately 907.18474 kilograms. It is the standard bulk commodity unit for coal, steel, cement, and freight in the United States. The "short" qualifier distinguishes it from the UK long ton (2,240 lb) and metric ton (1,000 kg).
One of the oldest English weight units, the stone was referenced as early as the 13th century. Historically its value varied by commodity (8 lb for meat, 12 lb for hemp, 14 lb for wool, 16 lb for glass). King Edward III standardised the wool stone at 14 pounds in 1350, which became the universal English standard. The Weights and Measures Act 1835 formally defined the stone as 14 lb. EU harmonisation abolished the stone for trade in 1985.
Interesting fact: The world record heaviest person weighed 635 kg — exactly 100 stone, illustrating how the stone unit provides digestible reference points for large body weights. British people typically express their weight as, for example, "11 stone 4 pounds."
The short ton emerged in the United States as commerce adopted 2,000 pounds as a round-number bulk standard, diverging from the British 2,240-lb long ton. It was codified in the US Customary system in the 19th century. US coal production, steel output, and grain yields are still reported in short tons domestically, though international trade uses metric tons. The US is one of only three countries (with Myanmar and Liberia) not officially on the metric system.
Interesting fact: A fully loaded standard US freight car carries approximately 100 short tons of cargo. The US historically produced ~1 billion short tons of coal per year; modern US coal consumption has fallen to about 400–500 million short tons annually.
