How many pounds in a stone and where did this measurement come from?
Tags: pounds, Stone
A stone is a unit of mass in the Imperial system of weights and measures used in the United Kingdom, Ireland, and most Commonwealth countries. It is equal to 14 pounds avoirdupois, or 6.35029318 kilograms.Though no longer an official unit of measure – in medical and other technical contexts kilograms are used – the stone remains almost universally popular for use in Britain and Ireland as a means of expressing human body weight. People in these countries would normally describe themselves as weighing, for example, "11 stone 4" (11 stone and 4 pounds).It was also frequently used in the past for weighing agricultural commodities. Potatoes, for example, were traditionally sold in stones or half-stones (14-pound or 7-pound quantities).
In the United States and Canada, where stone as a unit of weight is generally unknown, people would normally describe themselves as weighing "158 pounds" (using the same amount of weight as in the previous example). This usage of pounds alone to express body weight is very unusual in Britain and Ireland.

Stone is a unit of measure which, at the time it ceased to be legal for trade in United Kingdom in 1985, was defined in British legislation as being a weight or mass [sic] equal to 14 avoirdupois pounds (about 6.35 kilograms). It was also formerly used in several Commonwealth countries. The stone was originally used for weighing agricultural commodities. Historically the number of pounds in a stone varied by commodity, and was not the same in all times and places even for one commodity. Potatoes, for example, were traditionally sold in stone and half-stone (14-pound and 7-pound) quantities.
14-pound 6.350 kilograms.
