Stone: (abbreviation: st) is a unit of mass that is primarily used in the United Kingdom and Ireland to measure body weight. Although it is considered part of the imperial system, its use is largely limited to a few specific contexts today.
The stone as a unit of weight has been used since antiquity, with its value varying regionally depending on the commodity being measured. It became standardized in the 14th century in England, where it was fixed at 14 pounds for weighing wool, a major commodity at the time. Ounce: (symbol: oz) is a unit of weight (or mass) commonly used in the United States customary system and the British imperial system. It has different definitions depending on the context, such as the avoirdupois ounce and the troy ounce, each with its own specific applications.

Troy Ounce (oz t) - Used primarily for weighing precious metals like gold, silver, and platinum. And is slightly heavier than an avoirdupois ounce at 31.1035 grams (g).
