Microinch: A Unit of Length
The microinch is a unit of length that is equal to one millionth of an inch (0.000001 inch). It is a non-SI 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 Microinch
The 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 Microinch
The 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 Microinch
The 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 Units
The 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:
1 µin / 1,000,000 = 0.000001 in
1 µin / 12,000,000 = 8.333 × 10^-8 ft
1 µin / 36,000,000 = 2.778 × 10^-8 yd
1 µin x 2.54 × 10^-8 = 2.54 × 10^-8 m
1 µin x 2.54 × 10^-14 = 2.54 × 10^-14 km
1 µin x 25.4 = 25.4 nm
1 in x 1,000,000 = 1,000,000 µin
1 ft x 12,000,000 = 12,000,000 µin
1 yd x 36,000,000 = 36,000,000 µin
1 m / 2.54 × 10^-8 = 39,370,078.74 µin
1 km / 2.54 × 10^-14 = 39,370,078,740,157.48 µin
1 nm / 25.4 = 0.03937 µin
Meter - Unit of Distance / Length
Unit Symbol / Abbreviation: m
Where the unit used in the World:
The meter is used as a unit to measure medium distances or lengths.
Definition of the Unit:
The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).
History of the Unit:
As a result of the French Revolution in 1789, the old units of measure that were associated with the monarchy were replaced by the new units. The new unit of length was introduced which became known as the meter. In 1795 the meter was defined as 1/10,000,000 part of the quarter of a meridian, passing through Paris. The meter gained popularity in continental Europe during the nineteenth century, particularly in scientific field, and was officially adopted as an international measurement unit in 1875. In 1960 the meter was defined as 1,650,763.73 wavelengths of light from a specified transition in krypton-86. In 1983 the final definition of meter was accepted as length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
Where it's used:
The meter is commonly used in different trades and industries (for examle in machinery manufacturing), on road signs to indicate vehicle hight limits, the distance to short travel to a given location (for example in automotive GPS navigation voice prompts), on maps to indicate small scale, for vehicle, vessels and aircragt dimensions in industry and trade. It is also the most popular unit for describing the retail estate distances and measurements (room sizes, floor measurements and so on).
Equivalents in other units and scales:
1 m is equivalent to 3.28084 ft or 1.09361 yd.
