Standards of China

traditional system of measurement used by Han Chinese

The zhàng () is a customary Chinese unit of length equal to 10 chi (Chinese feet). Its value varied over time and place with different values of the chi, although it was occasionally standardized. In 1915, the Republic of China set it equal to about 3.2meters or 3.50yards. In 1930, this was revised to an exact value of 3⅓meters (about 3.645yd).
