Century Dictionary and Cyclopedia

  1. n. A system of weight in which one pound contains 16 ounces. It was introduced into England from Bayonne about a. d. 1300, and is substantially the Spanish system. In avoirdupois weight 7,000 troy grains (formerly, and now in the United States, approximately, but in Great Britain exactly) make a pound, while in troy weight the pound contains 5,760 grains, the grain being the same in both cases; hence, 175 pounds troy are equal to 144 pounds avoirdupois. The pound avoirdupois is the standard weight of Great Britain, and is equal to 453.6 grams in the French metric system. Avoirdupois weight is used in determining the weights of all commodities except gems and the precious metals. It is reckoned as follows: Cwt.Qrs.Pounds.Ounces.Drams. 1 ton= 20= 80= 2240= 35840= 573440 1 hundred weight= 4= 112= 1792= 28672 1 quarter= 28= 448= 7168 1 pound= 16= 256 1 ounce= 16 In the United States the hundredweight is now commonly 100 pounds, and the ton 2,000 pounds, called the short ton in distinction from the long ton of 2,240 pounds.
  2. n. The weight of anything according to the avoirdupois system: as, his avoirdupois was 150 pounds.
  3. n. Also written averdupois, and often abbreviated to avoir. and avdp.

  • chained_bear A Sea of Words: "The standard system of weights used in Great Britain for all goods except precious metals, precious stones, and medicines. The avoirdupois pound contains 7,000 grains. The avoirdupois weight of the U.S. agrees with that of Great Britain in the pound, ounce, and dram, but the U.S. hundredweight contains 100 pounds and the British hundredweight 112 pounds; the ton, 20 hundredweights, differs accordingly in the U.S. and Britain."
