About Ounce (oz)
An imperial unit of mass equal to 1/16 of a pound (approximately 28.35 grams). Ounces are the everyday small-mass unit in the US for food portions, boxing-glove weights, ingredient measurements in American cookbooks, and postal rates for small packages. The avoirdupois ounce used here is distinct from the troy ounce (~31.1 g) used exclusively for precious metals — a common source of confusion when comparing gold or silver quotes to grocery scales.
About Stone (st)
A British imperial unit of mass equal to 14 pounds (about 6.35 kilograms). The stone is still the everyday unit for personal body weight in the United Kingdom and Ireland — where people say "I weigh 12 stone" rather than 168 pounds or 76 kilograms. Officially abolished from UK commerce in 1985, the stone nonetheless remains cultural shorthand on British bathroom scales, medical charts, and casual conversation about weight. Equine and livestock weights in Britain are also still sometimes quoted in stones.
