In 1915, the Republic of China set it equal to about 3.2 meters or 3.50 yards.
In 1930, this was revised to an exact value of 3⅓ meters (about 3.645 yd).
It is not commonly used in mainland China today but appears in traditional Chinese architecture, where it was commonly used to measure bays.
In Japanese units of measurement, the jō (丈) is equivalent to ten shaku, or 3.03 meters.
