Extended data:

The unit of length refers to the basic unit for measuring spatial distance, which is formulated by human beings to standardize the length.

In the international system of units, the standard unit of length is "meter", which is represented by the symbol "m". 1960 11th international metrology conference: "The length of the meter is equal to 10 and 5d 1 of krypton -86 atom radiation, which is 1650763.73 times of the wavelength in vacuum".

Other length units are: light year, astronomical unit, meter (Pm), megameter (mm), kilometer (km), decimeter (dm), centimeter (cm), millimeter (Mm), silk rice (dmm), millet (cmm), micron (micron) and nanometer (nm).

In addition, a unit Egstrom (abbreviated as Egstrom, symbol? ) is a unit of length. It is not SI unit, but it can be converted by SI unit, that is, 1? = 10(- 10)m = 0. 1nm。 Generally used for atomic radius, bond length and visible light wavelength.
