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 Pounds
The avoirdupois pound (lb) is the primary unit of weight in the United States and United Kingdom for everyday use, equal to 16 ounces or exactly 453.59237 grams. It dominates American life: body weight, grocery produce, deli counter cuts, freight shipping costs, gym weights, and building material quantities are all measured in pounds and ounces. American recipes use pounds for meat and large quantities. The pound derives from the Roman 'libra pondo' (a pound by weight) - hence both the symbol 'lb' (from libra) and the British currency symbol '£'.
