About Quarters
A quarter (qr) in the avoirdupois system equals 28 pounds or one quarter of a hundredweight - approximately 12.70 kg. Historically, quarters were used in British trade for measuring grain, wool, and other bulk commodities. The British quarter of grain (28 lb) was the standard purchase quantity at markets and mills throughout medieval and early modern England. In the US, the term 'quarter' sometimes refers to a quarter of a short hundredweight (25 lb) rather than the British 28 lb.
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.
