A Dictionary of Units of Measurement_. See: http://www.unc.edu/~rowlett/units/dictS.html Here's what it says: stone (st) a traditional British unit of weight, rarely used in the U.S. Originally the stone varied in size, both from place to place and according to the nature of the item being weighed. A stone of sugar was traditionally 8 pounds, while a stone of wool could be as much as 24 pounds. Eventually the stone was standardized at 14 pounds avoirdupois or approximately 6.35029 kilograms - a convenient size because it makes the stone equal to exactly 1/2 quarter or 1/8 hundredweight. Today the stone is used mostly for stating the weight of persons or animals. No -s is added for the plural. - Doctor Sarah, The Math Forum http://mathforum.org/dr.math/
