https://en.wikipedia.org/wiki/Jin_(mass)The jin (Chinese: 斤; pinyin: jīn) or catty (from Malay kati) is a traditional Chinese unit of mass used across East and Southeast Asia, notably for weighing food and other groceries. Related units include the picul (dan/shi), equal to 100 catties, and the tael (liang), which is 1⁄16 of a catty. A stone (also dan/shi) is a former unit used in Hong Kong equal to 120 catties and a gwan (鈞) is 30 catties.
