      [Colloq.]
      [1913 Webster]
   Avoirdupois weight, a system of weights by which coarser
      commodities are weighed, such as hay, grain, butter,
      sugar, tea.
      [1913 Webster]
   Note: The standard Avoirdupois pound of the United States is
         equivalent to the weight of 27.7015 cubic inches of
         distilled water at 62[deg] Fahrenheit, the barometer
         being at 30 inches, and the water weighed in the air
         with brass weights. In this system of weights 16 drams
         make 1 ounce, 16 ounces 1 pound, 25 pounds 1 quarter, 4
         quarters 1 hundred weight, and 20 hundred weight 1 ton.
         The above pound contains 7,000 grains, or 453.54 grams,
         so that 1 pound avoirdupois is equivalent to 1 31-144
         pounds troy. (See Troy weight.) Formerly, a hundred
         weight was reckoned at 112 pounds, the ton being 2,240
         pounds (sometimes called a long ton).
         [1913 Webster]
