About these units
Quarter (US) (qr (US))
The US quarter equals 25 pounds, serving as a smaller commercial subdivision of the hundredweight. It was used for pricing agricultural goods, livestock feed, and some industrial materials. Its convenience arises from the fact that four quarters make a hundredweight, simplifying scaling between small and medium quantities. Today it is mostly of historical interest, but agricultural economists still encounter it when analyzing archival data.
Sun's Mass (M☉)
The Sun's mass, approximately 1.9885 × 10³⁰ kilograms, dominates the solar system, comprising 99.86% of all its mass. Solar mass controls planetary orbits, defines the structure of the heliosphere, and fuels stellar fusion reactions that sustain life on Earth. Astronomers use the solar mass as a comparative unit for other stars, star clusters, and black holes, making it one of the most important astronomical constants.
