About Solar Masses
A solar mass (M☉) is the mass of our Sun - approximately 1.989 × 10³⁰ kg - and is the standard unit for measuring stellar and galactic masses in astronomy. The Sun contains 99.86% of the total mass of the Solar System. Stellar evolution models describe stars of 0.08 M☉ (the minimum for hydrogen fusion) to over 200 M☉ (the most massive known stars). Supermassive black holes at the centres of galaxies range from millions to billions of solar masses: the black hole at the centre of the Milky Way (Sagittarius A*) is approximately 4.3 million M☉.
About Long Hundredweights
A long hundredweight (long cwt) equals 112 pounds or approximately 50.802 kg - equal to 8 stone. The standard hundredweight in the United Kingdom and much of its historical trading sphere, it reflects the medieval English stone of 14 lb (8 × 14 = 112). British agricultural commodity prices, wool trade records, and livestock market reports historically used long hundredweights. The UK meat trade still occasionally references hundredweights in wholesale pricing.
