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.
Electron Mass (Rest)
The electron mass (rest) is the invariant mass of an electron, approximately 9.10938356 × 10⁻³¹ kilograms, representing the mass of an electron at rest.
History/Origin
The electron mass was first measured in the early 20th century through experiments involving cathode rays and later refined with advancements in particle physics, establishing it as a fundamental constant in physics.
Current Use
The electron mass is used in calculations involving atomic and subatomic physics, quantum mechanics, and in defining units related to particle properties, such as in the 'Weight and Mass' converter for scientific and educational purposes.
