Pound (Troy or Apothecary)


The Troy pound is a traditional unit of weight used primarily in precious metals like gold, silver, and gemstones. Originating from the medieval French town of Troyes, it differs from the common avoirdupois pound. One troy pound equals 12 troy ounces, with each troy ounce weighing about 31.1 grams, making the troy pound approximately 373.24 grams.


Similarly, the apothecary pound was historically used in pharmacy and medicine for measuring ingredients. It also consists of 12 ounces but is slightly different in weight compared to the troy system. Both systems were crucial before the widespread adoption of the metric system and are still used today in specific fields for precision weighing.
