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.
Proton Mass
The proton mass (m_p) is the mass of a proton, a subatomic particle found in the nucleus of an atom, approximately 1.6726219 × 10⁻²⁷ kilograms.
History/Origin
The proton mass was first measured in the early 20th century through experiments involving atomic and nuclear physics, notably by Ernest Rutherford and subsequent researchers refining the value through scattering experiments and mass spectrometry.
Current Use
The proton mass is used as a fundamental constant in physics and chemistry, serving as a standard unit of mass in atomic and nuclear calculations, and is essential in defining atomic mass units and understanding nuclear reactions.
