Weights and measures

重量及容量 〔重量及容量〕 zhòng liàng jí róng liàng

Chinese weights and measure have changed in history in both name and in value.

Weights: Traditional units of weight in the modern era are jīn, liǎng, qián, and fēn. In the People’s Republic of China, one jīn, now for convenience of calculation is set at 500 g, is divided into 16 liǎng. One liǎng is divided into ten qián, and one qián into 10 fēn. One dan, a measure no longer used, is 120 jīn. The metric equivalents of these units have varied over the centuries. In ancient times (e.g., Hàn Dynasty), jīn and liǎng were the main units of weight; there was no qián or fēn. One liǎng was divided into 12 zhū.

Measures: Traditional units of volume are now virtually obsolete. The basic unit is the shēng. One shēng is a tenth of a dǒu (also called dipper) and is divided into ten gě. In ancient times, there was also a qián-spoon and square-inch spoon.
