Stone (st)
Definition: The stone (st) is a British unit of mass equivalent to 14 pounds, or approximately 6.35 kilograms. It is mainly used in the UK and Ireland for measuring body weight and, historically, agricultural produce and trade goods.
History: The stone has been used in Europe for centuries, with varying values depending on the region and commodity measured. The British stone was standardized at 14 pounds in 1835 under the Weights and Measures Act, primarily for weighing people and livestock. While largely replaced by metric units, it remains popular in sports and healthcare.
Current Use: The stone is still used in the UK and Ireland to express body weight, especially in medical and fitness contexts. It is less common in trade but occasionally used for measuring wool and agricultural products.
US Short Ton
Definition: The US short ton is a unit of mass equal to 2,000 pounds (approximately 907.184 kilograms). It is commonly used in the United States for industrial, construction, and freight measurements.
History: The US ton evolved from British weight standards but was adapted to a simpler 2,000-pound definition in the 19th century. This made calculations easier for commerce and industry. Unlike the UK long ton, the US short ton was not influenced by the British imperial system but remained a domestic standard.
Current Use: The US ton is extensively used in the shipping, construction, and manufacturing industries. It appears in cargo shipping, material weight specifications, and fuel measurements, particularly in the United States where metric adoption is limited.
