Commonly used length units are: kilometers {kilometers} (km), decimeters (dm), centimeters (cm), millimeters (mm), micrometers (μm), nanometers (nm), picometers (pm), femtometers ( fm).
(1) km
Kilometer, also known as kilometer, is a unit of length, abbreviated as "km", usually used to measure the distance between two places. The usual conversion relationship is as follows: 1 kilometer (km) = 1,000 meters (meters) = 100,000 centimeters (cm) = 1,000,000 millimeters (mm); 1.61 kilometers = 1 mile.
(2) Decimeter
Decimeter (decimeter or dm) is one of the metric units of length, and one decimeter is equivalent to one tenth of a meter. The commonly used conversion relationship is as follows: 1 decimeter = 0.0001 kilometers (km) = 0.1 meters (m) = 10 centimeters (cm) = 100 millimeters (mm).
(3) cm
Centimeter, length unit; English: centimetre(s), abbreviation (symbol) is: cm. The unit conversion of centimeters is as follows: 1 centimeter = 10 millimeters = 0.1 decimetres = 0.01 meters = 0.00001 kilometers.
(4) mm
Millimeter, also called millimeter (or millimeter) in English, is a unit of length and rainfall, symbol ㎜. One millimeter is equivalent to one thousandth of a meter (this is the meaning of "millimeter"). The system relationship is as follows: 1 millimeter = 0.1 cm = 0.01 decimeter = 0.001 meter = 0.000001 kilometers.
(5) Micron
Micron is a unit of length, [micron], the symbol u, pronounced [miú]. One micrometer is equivalent to one millionth of a meter (this is the meaning of "micro"). The conversion relationship is as follows: 1 micron (μm) = 1 000 nanometers (nm) = 0.001 millimeters (mm) = 0.000 1 centimeters (cm). Because m has been used as an abbreviation for millimeters, use u (understand by yourself)
Nanometer (nm) is the translation of nanometer, bai is nanometer, and the unit of measurement for length du. The symbol of the international system of units is nm. 1 nanometer = 10^-9 meters, the unit of length is the same as centimeters, decimeters and meters, it is the unit of measurement of length. Equivalent to 4 times the size of an atom, much smaller than the length of a single bacterium. The international common name is nanometer, abbreviated as nm.
