How to convert1 micron (µ) = 39.37007874 microinch (µin). Micron (µ) is a unit of Length used in Metric system. Microinch (µin) is a unit of Length used in Standard system. 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. Example Conversions of Micron to Other UnitsHere are some examples of converting micron to other units of length:
Microinch: A Unit of LengthThe microinch is a unit of length that is equal to one millionth of an inch (0.000001 inch). It is a nonSI unit of measurement that is mainly used in engineering and manufacturing fields. The symbol for microinch is µin or µ". The microinch is also a derived unit in the British imperial and US customary systems of measurement. The microinch is most commonly used when expressing small distances or dimensions, such as the surface roughness or flatness of materials and parts. The microinch is also used for measuring the wavelength of light and other electromagnetic waves. In this article, we will explore the definition, history, usage and conversion of the microinch as a unit of length. Definition of the MicroinchThe microinch is a unit of length that is equal to one millionth of an inch (0.000001 inch). It is defined as 25.4 nanometers or 2.54 × 10^8 meters by international agreement in 1959. One inch is equal to 25.4 millimeters or 0.0254 meter. The definition of the microinch has changed over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the microinch as based on the meter was agreed upon by an international treaty in 1959. History of the MicroinchThe origin of the microinch as a unit of length can be traced back to the early 20th century, when it was introduced by the American Society for Testing and Materials (ASTM) as a standard for measuring surface roughness. Surface roughness is a measure of how smooth or irregular a surface is, which affects its friction, wear and corrosion properties. The microinch was adopted by other countries and industries that followed the American system of measurement, such as Canada and Japan. It was also incorporated into the ANSI/ASME B46.1 standard for surface texture in 1985. The microinch was also used by some optical scientists and engineers to measure the wavelength of light and other electromagnetic waves. For example, the visible spectrum of light ranges from about 4,000 to 7,000 microinches. Usage of the MicroinchThe microinch is a unit of length that is used for measuring small distances or dimensions, such as the surface roughness or flatness of materials and parts. For example:
The microinch is commonly used in engineering and manufacturing fields, especially in precision machining, metrology and quality control. Some examples are:
The microinch is also used for measuring the wavelength of light and other electromagnetic waves. For example:
Example Conversions of Microinch to Other UnitsThe microinch can be converted to other units of length by using different factors and formulas. Here are some examples of conversion for different types of units:
