About Kilotonnes
A kilotonne (kt) equals 1,000 metric tonnes (10⁶ kg). In military and geopolitical contexts, nuclear weapon yields are expressed in kilotons of TNT equivalent (kt TNT): the atomic bomb dropped on Hiroshima had a yield of approximately 15 kt TNT. Environmental science uses kilotonnes for reporting regional greenhouse gas inventories, industrial pollutant releases, and annual waste generation. Mining operations quote ore extraction rates in kilotonnes per day. The global atmospheric inventory of various trace gases is reported in kilotonnes.
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.
