Carat
A carat is a unit of mass used to measure gemstones and pearls, equal to 200 milligrams.
History/Origin
The carat originated from the carob seed, which was historically used as a counterweight in balance scales due to its uniform weight. The term has been used since the 16th century to measure precious stones.
Current Use
Today, the carat is primarily used in the jewelry industry to specify the weight of diamonds and other gemstones, with 1 carat equaling 0.2 grams.
Atomic Mass Unit
The atomic mass unit (u) is a standard unit of mass used to express atomic and molecular weights, defined as one twelfth of the mass of a carbon-12 atom.
History/Origin
The atomic mass unit was introduced in the early 20th century to provide a convenient scale for atomic weights. It was originally based on the mass of hydrogen but was later standardized to be one twelfth of the mass of a carbon-12 atom, which was adopted as a reference in 1961 by the IUPAC.
Current Use
The atomic mass unit is widely used in chemistry and physics to express atomic and molecular masses, facilitating calculations in molecular chemistry, nuclear physics, and related fields.
