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.
Planck Mass
The Planck mass (m_P) is a fundamental physical constant representing a mass scale derived from natural units, approximately 2.176 × 10^-8 kilograms.
History/Origin
Introduced by Max Planck in 1899 as part of his system of natural units, the Planck mass emerged from combining fundamental constants to define a universal mass scale in theoretical physics.
Current Use
The Planck mass is primarily used in theoretical physics, especially in quantum gravity and high-energy physics, to express natural units and scale phenomena near the Planck scale.
