What are the traditional units of length measurement in China? What is the conversion relationship with the current international units?

▲ The traditional length units in China are: Li, Zhang, ruler, inch, ten-day, Fu, Zhi, Yi, Bu, Chang, Ya, Yan, Ji, Rail, Pheasant, Millimeter, Li and Minute.

1 Li = 150 sheets = 500m.

2 Li = 1 km (1000m)

1 ft = 10 ft,

1 foot = 10 inch.

1 inch = 10 point.

1 = 10%.

1 sheet = 3.33m,

1 ft =3.33 decimeters,

1 inch =3.33 cm.

1 km =1000m

1 meter (m) = 100 cm

1 cm =10mm

The unit of length refers to the basic unit for measuring spatial distance, which is formulated by human beings to standardize the length. Its international unit is "meter" (symbol "m"), and commonly used units are millimeter (mm), centimeter (cm), decimeter (dm), kilometer (km) and so on. Length units play an important role in various fields.

▲ In the international system of units, the standard unit of length is "meter", which is represented by the symbol "m". 1960 The 1st International Metrology Conference: "The length of the meter is equal to 1650763.73 times of the radiation wavelength passing between 2P 10 and 5d 1 levels of krypton -86 atoms in vacuum".
