[[File:Gilded Bronze Ruler - 1 chi = 231 cm. Western Han (206 BCE - CE 8). Hanzhong City.jpg|thumb|Gilded Bronze Ruler - 1 ''[[chi (length)|chi]]'' = 231 mm. [[Western Han]] (206 BCE–8 CE). [[Hanzhong City]]]]
Traditional units of length include the ''[[chi (unit)|chi]]'' ({{lang|zh|尺}}), ''bu'' ({{lang|zh|步}}), and ''[[li (length)|li]]'' ({{lang|zh|里}}). The precise length of these units, and the ratios between these units, has varied over time. 1 ''bu'' has consisted of either 5 or 6 ''chi'', while 1 ''li'' has consisted of 300 or 360 ''bu''.
