About Stones
A stone (st) equals 14 pounds or approximately 6.350 kg. It is the standard unit for expressing human body weight in the United Kingdom and Ireland, where a person will say they weigh '11 stone 4' (meaning 11 stone and 4 pounds, or 158 lb / 71.7 kg). Despite the UK's official adoption of the metric system, stones remain the dominant unit for personal body weight on British bathroom scales, in doctors' offices, and in everyday conversation. British newspapers and sports reports routinely describe athletes' weights in stones and pounds.
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.
