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 Tons
A short ton (also known as a US ton) equals exactly 2,000 pounds or approximately 907.185 kg. It is the standard ton in the United States for coal, scrap metal, aggregate, freight, and agricultural commodities. US electricity, energy, and mining production statistics are reported in short tons or millions of short tons (MMst). American trucking weight limits, rail car capacities, and bulk cargo specifications use short tons. When Americans refer to a 'ton' without qualification, they almost always mean the short ton.
