CHANG

Pinyin Zhang, an old Chinese measure of length equal to 10 ch'ih, or 3.58 m (11 feet 9 inches). The value was agreed upon by China in treaties (184244 and 185860) with England and France. It was thereafter used by Chinese maritime customs as the standard value for assessing all tariff duties. The length of one ch'ih varied throughout China from 27.9 to 40 cm (11 to 15.8 inches). The so-called treaty ch'ih was defined for customs purposes as 35.8 cm (14.1 inches).
