Pound (lbs)
Definition: The pound (lbs) is a unit of mass commonly used in the United States and the United Kingdom. It is officially defined as exactly 0.45359237 kilograms. The pound remains a key weight measurement in various fields, including trade, cooking, and sports.
History: The pound has origins in Roman and medieval systems. The Roman libra (from which 'lbs' is derived) influenced various European weight standards. Over time, the British and American systems evolved independently, with the UK adopting the avoirdupois pound in 1824. The international pound was standardized in 1959 to align with metric conversions, ensuring consistency across different regions.
Current Use: The pound is widely used in the US and UK for body weight, grocery items, and postal services. It also appears in aviation, sports (boxing and wrestling), and commercial trade, particularly where metric adoption is incomplete.
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.
