About Ounces

The avoirdupois ounce (oz) is 1/16 of a pound, equal to approximately 28.35 grams. It is the everyday ounce used in the United States and United Kingdom for food portions, household quantities, and general trade. US food packages, recipe measurements, and nutrition labels reference ounces; a standard stick of butter is 4 oz, a can of soup typically 10.75 oz, and a baseball weighs 5-5.25 oz. Unlike the troy ounce (31.10 g) used for precious metals, the avoirdupois ounce (28.35 g) is lighter.

About Stones

A stone (st) equals 14 pounds or approximately 6.350 kg. It is the standard unit for expressing human body weight in the United Kingdom and Ireland, where a person will say they weigh '11 stone 4' (meaning 11 stone and 4 pounds, or 158 lb / 71.7 kg). Despite the UK's official adoption of the metric system, stones remain the dominant unit for personal body weight on British bathroom scales, in doctors' offices, and in everyday conversation. British newspapers and sports reports routinely describe athletes' weights in stones and pounds.
