<P> STONE also denotes a certain quantity or weight of some commodities . A stone of beef, in London, is the quantity of eight pounds; in Hertfordshire, twelve pounds; in Scotland sixteen pounds . </P> <P> The Weights and Measures Act of 1824, which applied to all of the United Kingdom, consolidated the weights and measures legislation of several centuries into a single document . It revoked the provision that bales of wool should be made up of 20 stones, each of 14 pounds, but made no provision for the continued use of the stone . Ten years later, a stone still varied from 5 pounds (glass) to 8 pounds (meat and fish) to 14 pounds (wool and "horseman's weight"). However, the Act of 1835 permitted using a stone of 14 pounds for trade but other values remained in use . James Britten, in 1880 for example, catalogued a number of different values of the stone in various British towns and cities, ranging from 4 lb to 26 lb . The value of the stone and associated units of measure that were legalised for purposes of trade were clarified by the Weights and Measures Act 1835 as follows: </P> <Table> <Tr> <Th> Pounds </Th> <Th> Unit </Th> <Th> Stone </Th> <Th> kg </Th> </Tr> <Tr> <Td> </Td> <Td> 1 pound </Td> <Td> ​ ⁄ </Td> <Td> 0.4536 </Td> </Tr> <Tr> <Td> 14 </Td> <Td> 1 stone </Td> <Td> </Td> <Td> 6.350 </Td> </Tr> <Tr> <Td> 28 </Td> <Td> 1 quarter </Td> <Td> </Td> <Td> 12.70 </Td> </Tr> <Tr> <Td> 112 </Td> <Td> 1 hundredweight </Td> <Td> 8 </Td> <Td> 50.80 </Td> </Tr> <Tr> <Td> 2240 </Td> <Td> 1 (long) ton </Td> <Td> 160 </Td> <Td> 1016 </Td> </Tr> </Table> <Tr> <Th> Pounds </Th> <Th> Unit </Th> <Th> Stone </Th> <Th> kg </Th> </Tr>
