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 Milligrams
A milligram (mg) is one thousandth of a gram (10⁻³ g). It is the primary unit for pharmaceutical dosing: aspirin tablets are typically 500 mg, ibuprofen 200-400 mg, and melatonin supplements 0.5-10 mg. Precious metal assay results and alloy compositions are specified in milligrams per kilogram (mg/kg = ppm). Nutritional labels worldwide list mineral content in milligrams - the recommended daily intake of iron is 8-18 mg, calcium 1000 mg, and sodium under 2300 mg. A grain of rice weighs about 25-30 mg, and a medium eyelash approximately 0.1 mg.
