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 Kilograms
The kilogram (kg) is the SI base unit of mass - the fundamental unit from which all other mass measurements in the metric system are derived. Since 2019 it has been defined by fixing the Planck constant h to exactly 6.62607015 × 10⁻³⁴ J·s, replacing the 130-year-old International Prototype Kilogram (a platinum-iridium cylinder kept in Sèvres, France). The kilogram governs daily life worldwide: body weight in most countries, grocery shopping, luggage allowances, postal rates, freight pricing, and ingredient quantities in cooking all reference kilograms.
