or Avoirdupois weight, a sort of weight used in England, the pound whereof is made up of fifteen ounces. See Weight.

This is the weight for the larger and coarser commodities, such as groceries, cheese, wool, lead, &c. Bakers, who live not in corporation-towns, are to make their bread by avoirdupois-weight, those in corporations by troy weight. Apothecaries buy by avoirdupois-weight, but sell by troy. The proportion of a pound avoirdupois to a pound troy is as 17 to 14.
