About Pennyweights

A pennyweight (dwt or pwt) equals 24 grains or 1/20 of a troy ounce - approximately 1.555 grams. Its name derives from the weight of an English silver penny in the medieval period. Pennyweights are the standard unit used by jewellers and goldsmiths in North America for weighing precious metals: gold, silver, and platinum. When a jeweller quotes the gold weight of a ring or chain, they typically use pennyweights. Gold buyers, refiners, and scrap metal dealers quote prices per pennyweight (often abbreviated 'DWT') when appraising jewellery.

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.
