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 Carats
A metric carat (ct or CD) is exactly 200 milligrams (0.2 g), the universal standard for weighing gemstones. Established internationally in 1907, it replaced fractionally different regional carat weights previously used in different countries. The total weight of a diamond or colored gemstone is always expressed in carats: a 1.00 ct diamond of excellent cut and color can command over $5,000. The Cullinan diamond, the largest gem-quality rough diamond ever found, weighed 3,106.75 carats.
