1. Avoirdupois:
The
Avoirdupois system was widely used in most English-speaking countries for the general
weighing of goods, except for precious metals, gems and drugs. The U.S. still uses this
system for most items of retail trade, but is considering moving toward the metric system.
This system remains in some use in Britain despite the introduction of metric units there.
