How to convert1 micrometer (µm) = 1 micron (µ). Micrometer (µm) is a unit of Length used in Metric system. Micron (µ) is a unit of Length used in Metric system. Micrometer: A Unit of LengthDefinition of the micrometerThe micrometer, also known as the micron, is a unit of length in the International System of Units (SI) that equals one millionth of a meter. Its symbol is µm. History of the micrometerThe term micron and the symbol µ were officially accepted for use in isolation to denote the micrometer in 1879, but officially revoked by the International System of Units (SI) in 1967. This became necessary because the older usage was incompatible with the official adoption of the unit prefix micro, denoted µ, during the creation of the SI in 1960. In the SI, the systematic name micrometre became the official name of the unit, and µm became the official unit symbol. How to convert micrometerThe micrometer can be converted to other units of length using simple multiplication or division by powers of 10. For example, one micrometer is equal to 0.001 millimeters, 0.000001 meters, or 0.000000001 kilometers in the SI system. One micrometer is also equal to 0.000039 inches, 0.0000033 feet, or 0.00000062 miles in the US standard system. Where micrometer is usedThe micrometer is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibers. The width of a single human hair ranges from approximately 20 to 200 µm The micrometer is used in different countries and applications for various purposes. For example:

Micron: A Unit of LengthA micron is a unit of length that is equal to one millionth of a meter. It is also known as a micrometer or a micrometre. The symbol for micron is µm. How to Convert MicronTo convert micron to other units of length, we need to use some conversion factors. Here are some common conversion factors for US Standard system and SI system:
Using these conversion factors, we can multiply or divide the number of microns by the appropriate factor to get the equivalent length in another unit. For example:
Where Micron is UsedThe micron is used in various fields and applications that require measuring very small distances or sizes. Some examples are:
The use of micron varies by country and region. For example:
Definition of the MicronThe micron is defined as one millionth of a meter. A meter is the base unit of length in the SI system. The SI system is an international system of units that is based on seven fundamental quantities: length, mass, time, electric current, temperature, luminous intensity, and amount of substance. The meter was originally defined as one tenmillionth of the distance from the equator to the North Pole along a meridian. However, this definition was not very precise and practical. Therefore, over time, the definition of the meter has changed several times based on different physical constants and standards. The current definition of the meter was adopted in 1983 by the General Conference on Weights and Measures (CGPM). It states that: The meter is the length of the path travelled by light in vacuum during a time interval of 1/299792458 second. Using this definition, we can derive that one micron is equal to: 1 µm = (1/299792458) / (1000000) second * (299792458 m / second) = (1/1000000) m = 0.000001 m History of MicronThe micron was first introduced in the late 18th century by French scientists who were developing a decimal system of units. They proposed a unit called micrometre that was equal to one millionth of a meter. However, this unit was not widely accepted or used at that time. In the early 19th century, British scientists adopted a similar unit called microinch that was equal to one millionth of an inch. This unit was more popular among Englishspeaking countries and regions. In the late 19th century, German scientists proposed a new unit called mikrometer that was also equal to one millionth of a meter. This unit was more consistent with the metric system and became more widely used in Europe and Asia. In the early 20th century, the International Bureau of Weights and Measures (BIPM) recommended using the term micrometer instead of micron or mikrometer to avoid confusion with other units. However, many people still preferred using micron as a shorter and simpler name. In 1960, the CGPM adopted the SI system as the official system of units for science and technology. The SI system used the term micrometer as the official name for the unit of length equal to one millionth of a meter. The symbol for micrometer was also standardized as µm. However, the term micron and its symbol µ were still widely used in many fields and applications. Therefore, in 1975, the CGPM decided to allow the use of micron and µ as alternative names and symbols for micrometer and µm. However, they also stated that these alternatives should be avoided in official documents and publications.
