Carat (ct)
Definition: The carat (ct) is a unit of mass used for measuring gemstones and pearls. One carat is precisely 200 milligrams (0.2 grams). It ensures standardization in the valuation of diamonds, sapphires, and other precious stones.
History: The carat originates from the seeds of the carob tree, which were historically used as counterweights due to their uniform mass. The modern metric carat (200 mg) was standardized in 1907 to eliminate regional inconsistencies. This change facilitated international trade and valuation of gemstones.
Current Use: The carat is universally used in the jewelry and gemstone industries. It provides an accurate measurement for diamonds, emeralds, and other precious stones, ensuring fair pricing in global markets.
US Short Ton
Definition: The US short ton is a unit of mass equal to 2,000 pounds (approximately 907.184 kilograms). It is commonly used in the United States for industrial, construction, and freight measurements.
History: The US ton evolved from British weight standards but was adapted to a simpler 2,000-pound definition in the 19th century. This made calculations easier for commerce and industry. Unlike the UK long ton, the US short ton was not influenced by the British imperial system but remained a domestic standard.
Current Use: The US ton is extensively used in the shipping, construction, and manufacturing industries. It appears in cargo shipping, material weight specifications, and fuel measurements, particularly in the United States where metric adoption is limited.
