Convert Carat to Tonne
Carat
The carat (ct) is a unit of mass used to measure the weight of gemstones and pearls. One carat is equivalent to 200 milligrams or 0.2 grams. It is commonly used in the jewelry industry to indicate the size and weight of precious stones such as diamonds, rubies, and emeralds.
The carat originated from the use of the carob seed (from the Ceratonia siliqua tree) as a reference for weight in ancient times. These seeds were used because of their relatively consistent weight, and they were widely available across regions. The term "carat" comes from the Greek word "keration", which means "little horn," referring to the carob seed. Over time, the carat became standardized, and in 1907, the International Union of Pure and Applied Chemistry (IUPAC) defined the carat as 200 milligrams, ensuring consistency in the measurement of gemstones worldwide.
Tonne
The tonne (t) is a unit of mass equal to 1,000 kilograms (1,000 kg) or 1 megagram (1 Mg). It is part of the metric system but is not an SI unit. However, it is accepted for use with the SI due to its widespread application in measuring large masses, such as in industry and transportation.
The tonne was introduced in the 1790s during the creation of the metric system in France. It was established as a convenient way to represent large quantities of mass, aligning with the decimal-based nature of the system. The term "tonne" is derived from the Old French word "tonne", meaning a large cask or barrel, reflecting its use in measuring heavy loads. Over time, it became a standardized unit used globally in fields like shipping, agriculture, and environmental science.
