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 '£'.
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.
