Sun's Mass
The Sun's mass (M_sun) is a standard unit of mass used in astronomy to express the mass of other stars and celestial objects, approximately equal to 1.989 × 10^30 kilograms.
History/Origin
The concept of using the Sun's mass as a unit originated in the early 20th century as astronomers sought a convenient standard for stellar masses. It became widely adopted in astrophysics for its practicality and ease of comparison.
Current Use
Today, M_sun is commonly used in astrophysics and astronomy to describe the mass of stars, planets, and other celestial bodies, facilitating standardized communication and calculations within the scientific community.
Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
