One stone is equivalent to fourteen pounds or 6. 35 kilograms. Stones are used in Great Britain and Ireland commonly, though the 1985 Weights and Measures Act prohibited the measurement from being used in trade.
A stone (symbol: st) is a unit of measure formerly used in the United Kingdom and it corresponds to about 14 pounds (lb) which is consequently equal to 6. 35 kilograms.
A "stone" weighs 14 pounds. So, something that weighs 100 pounds would weigh 100/14 stone or a little over 7 stone. A weight of 100 stone would be 100 X 14 or 1400 pounds.
