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 Grams
The gram (g) is the basic metric unit of mass, equal to one thousandth of a kilogram. It is universally used in cooking, nutrition, postal services, and scientific measurement. Almost all food packaging worldwide shows nutritional information per 100 g. A US nickel coin weighs exactly 5 g, a teaspoon of sugar about 4 g, and a standard paperclip approximately 1 g. In chemistry, the gram is central to molar mass: one mole of carbon-12 atoms weighs exactly 12 g. Postal rates are typically scaled per gram or per 100 g.
