Units explained
Wey
The wey was an English bulk weight, here taken as 252 pounds (about 114.3 kg).
From Old English 'waege', a weighing or balance.
Obsolete English unit for wool, cheese, and salt.
Used in medieval and early-modern English trade.
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.
Wey to Sun's Mass conversion formula
