Units explained
Sun's Mass
The solar mass (M(S)) is about 2.0E30 kg.
The standard unit for expressing stellar and galactic masses.
Astrophysics and cosmology.
Established as astronomers measured the Sun's gravitational influence.
Grain
The grain (gr) equals 1/7000 of an avoirdupois pound, about 64.8 milligrams.
Based on the nominal mass of a single barley grain.
Ammunition and bullet mass, archery, and historical pharmacy.
Standardized through the English avoirdupois system and retained in 1959.
Sun's Mass to Grain conversion formula
Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.
