Micrometer to Kilometer Converter

Micrometer

A micrometer (symbol: μm) is a unit for measuring length. One micrometer equals to one millionth of a meter i.e. 0.000001 m. One micrometer can be expressed in scientific notation as 1×10⁻⁶ m.

Micrometer is often used to express length at the atomic levels. The micrometer is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria. The width of a single human hair ranges from approximately 20 to 200 μm. The longest human chromosome, chromosome 1, is approximately 10 μm in length.

Kilometer

A kilometer (symbol: km) consists of one thousand meters. The kilo prefix stands for 1000. Kilometer is often used in measuring geographical distances. For example, the distance between New York and London is approximately 5571.55 kilometers. In the United States, however, mile is the prefered unit for measuring these distances. Vehicle speed is often measured in km/hour units.
