Fact about Pound

Basic facts:  A pound is a unit of mass used in the United States customary and imperial systems of measurement. Its symbol is [lb.]. The common pound used today is the international avoirdupois pound. It is defined as precisely 0.45359237 kilograms. One avoirdupois pound is equal to 16 (sixteen) avoirdupois ounces.

History: Prior to the international avoirdupois pound that is widely used today, numerous different definitions of the pound were used throughout history. The pound descended from the Roman libra. The avoirdupois system was commonly used in the 13th century. In 1959, it was updated to its current form. This system was based on a physical standardized pound that used a prototype weight. This prototype weight could be divided into a number that had three even divisors [8, 4, 2] i.e., 16 ounces.

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

Facts about Stone

Basic Facts: Stone weight or the stone [symbol: st.] is an imperial and English unit of mass equivalent to 14 pounds [approx. 6.35 kg]. Europe’s various “stones” were replaced by or adapted to the kilogram from the mid-19th century on with the origin of metrication.

History: The term “stone” comes from the use of stones for weights, a practice that dates back into antiquity. In Roman periods stone weights were crafted to multiples of the Roman pound.

Use: The stone stays widely used in the United Kingdom and Ireland for human body weight. In those countries, people may typically be said to weigh, e.g., “11 stone 4” [11 stones and 4 pounds], instead of saying “158 pounds”, that is the conventional way of expressing the same weight in the United States or “72 kilograms” as used in most of the other countries. The stone is used to express body weights in many sports in both Britain and Ireland, such as professional wrestling, boxing, and horse racing. Germanic-speaking northern European countries and England formerly used various standardized “stones” for trade, with their values varying from about 5 to 40 local pounds [approx. 3 to 15 kg] depending on objects weighed and the location.
