Convert Solar Masses to Slugs
Convert Solar Masses (M☉) to Slugs (slug) instantly and accurately.
Conversion Formula
slug = M☉ × 1.362843105e+29
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 Slugs
A slug is a unit of mass in the British imperial and US customary foot-pound-second (FPS) engineering system, equal to the mass that accelerates at 1 foot per second squared under a force of 1 pound-force - approximately 14.594 kg. The slug was introduced to simplify dynamics calculations in engineering: using slugs ensures that F = ma holds without unit conversion factors when force is in pounds-force and acceleration in ft/s². Aerospace engineers and mechanical engineers working in US customary units use slugs for aircraft mass, structural dynamics, and ballistic calculations.
