In England, from at least 1340, “stone” has usually referred to a unit of mass = 14 pounds. For a discussion of the origin of the 14-lb stone, see sack. Use of the stone in trade was abolished by the Weights and Measures Act of 1985. Among other uses, a person's weight is often still expressed in stones with the remainder in pounds, for example, “6 stone 10.”
As late as 1862, however, over a dozen other definitions of the stone were in use in various trades and locations in the United Kingdom.
A stone of 5 pounds used for glass, mentioned in a document of 1302. It is also mentioned in Worlidge's dictionary (1704), which describes a 5-lb stone of grass, 24 of which make up a seam. “Grass” is probably a misprint for “glass.”
In the 13ᵗʰ century a stone of 8 pounds was used for spices and pharmaceuticals, “wax, sugar, pepper, cinnamon, nutmegs and alum.” By 1496, it was already referred to as being “of old time called the stone of London.” In the 1600s the 8-lb stone was still used for spices, but by 1700 it had become associated with butchers. The Weights and Measures Act of 1834 mentions it in passing as a unit to be suppressed in favor of a universal 14-lb stone. In 1934, 582 years after Edward III specified “every stone to weigh 14 lb,” the Board of Trade was writing its inspectors about “the old London or butcher's stone,” advising them “New machines [that is, scales] graduated in 8 lb units will be accepted for verification and stamping until 31 January 1935 it being understood, (1) that after that date no new machines so graduated are to be stamped.”
In Counties Armagh, Monaghan, Tyrone, and probably others, Ireland, 18ᵗʰ century, a stone of 16 pounds used for wool, feathers and tallow.
In County Down a stone of 16 pounds used for undressed and hackled flax.
In County Clare a stone of potatoes was 16 pounds in summer, but 18 pounds in winter.
