About Catties
The catty (also jin 斤 in Chinese) is a traditional unit of mass used across East and Southeast Asia, equal to 600 grams in its modern metric form. It was historically the standard unit of trade for goods at markets throughout China, Japan, Korea, and Southeast Asia for over a thousand years. Today the catty remains widely used in Chinese, Vietnamese, Malaysian, and Singaporean wet markets and grocery stores for weighing vegetables, meat, and fish. In Hong Kong, the catty (斤) is precisely 604.79 grams; in mainland China it is exactly 500 grams (half a kilogram).
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☉.
