The standard ton in the United Kingdom and Commonwealth countries, it equals 20 long hundredweights of 112 lb each. Naval architecture and ship displacement are specified in long tons: the displacement of a warship or cargo vessel is the weight of water it displaces, expressed in long tons. The Titanic had a displacement of approximately 52,310 long tons. British agricultural, mining, and coal trade statistics from the 18th through mid-20th centuries used long tons exclusively.
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.
