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 Micrograms
A microgram (µg or mcg) is one millionth of a gram (10⁻⁶ g). It is the standard dosing unit for potent medications and micronutrients: vitamin B12 recommended daily intake is 2.4 µg, folic acid supplements are 400 µg, and levothyroxine (thyroid medication) doses are typically 25-200 µg. Air quality standards measure fine particulate matter (PM2.5) in micrograms per cubic meter - the WHO guideline is 15 µg/m³ annual mean. A grain of sand weighs about 50-100 micrograms, and a single snowflake approximately 3 micrograms.
