Pound

Definition: A pound (symbol: lb) is a unit of mass used in the imperial and US customary systems of measurement. The international avoirdupois pound (the common pound used today) is defined as exactly 0.45359237 kilograms. The avoirdupois pound is equivalent to 16 avoirdupois ounces.

History/origin: The pound descended from the Roman libra, and numerous different definitions of the pound were used throughout history prior to the international avoirdupois pound that is widely used today. The avoirdupois system is a system that was commonly used in the 13th century. It was updated to its current form in 1959. It is a system that was based on a physical standardized pound that used a prototype weight. This prototype weight could be divided into 16 ounces, a number that had three even divisors (8, 4, 2). This convenience could be the reason that the system was more popular than other systems of the time that used 10, 12, or 15 subdivisions.

Current use: The pound as a unit of weight is widely used in the United States, often for measuring body weight. Many versions of the pound existed in the past in the United Kingdom (UK), and although the UK largely uses the International System of Units, pounds are still used within certain contexts, such as labelling of packaged foods (by law the metric values must also be displayed). The UK also often uses both pounds and stones when describing body weight, where a stone is comprised of 14 pounds.

Stone

Definition: A stone (symbol: st) is an English and imperial unit of mass. It is defined as 14 pounds or 6.35029318 kilograms.

History/origin: The name "stone" is derived from the use of stones as weights since antiquity. Standardized stones were historically used for trade in England as well as some countries in northern Europe. In England, the stone had multiple definitions throughout history, based on the commodity and on local standards. In 1350, the stone was standardized to be used for wool at a weight of 14 pounds, and in 1835, the United Kingdom adopted this definition for use in the imperial system.

Current use: The stone as a unit of mass is used mostly in the United Kingdom for measuring body weight. Most other countries measure body weight in kilograms, and in some cases, in pounds.
