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 Short Hundredweights
A short hundredweight (cwt, US cwt) equals exactly 100 pounds or approximately 45.359 kg. Used primarily in the United States for commodity trading, it represents the practical 'hundred-pound' unit for measuring coal, agricultural produce, livestock feed, and industrial materials. Commodity markets for cattle, hogs, and grain in the US price their products per hundredweight ($/cwt or $/100 lb). Steel and non-ferrous metal quotations in North America are commonly expressed in dollars per short hundredweight. The 'short' modifier distinguishes it from the UK long hundredweight (112 lb).
