The traditional units of length in China are Li, Zhang, Chi, Inch, Xun, Jie, Fu, Zhi, Yi, Bu, Chang, Ya, Yan, Ji, Rail, Luo, Millimeter, Li and Min. The basic transformation relationship is as follows:

1, 1 foot = 10 foot; 1 ft = 10 inch; 1 inch = 10 points; 1 = 10%;

2. 1 sheet ≈ 3.33m; 1 ft ≈3.33 decimeter; 1 inch ≈3.33 cm;

3. 1km = 1000m； 1 meter (m) = 100 cm; 1 cm =10mm

4. 1 Li = 150 sheets = 500m; 2 Li = 1 km (1000 m).

In the international system of units, the standard unit of length is "meter", which is represented by the symbol "m". The unit of length adopted in China is consistent with the international system of units, that is, "meter" is the legal unit of length measurement in China.
