How to convert

1 meter (m) = 39370100 microinch (µin). Meter (m) is a unit of Length used in Metric system. Microinch (µin) is a unit of Length used in Standard system.

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.
It's a standard measure for short distances (up to 1 km long), in real estate and construction, supply materials, vehicle and aircraft dimensions, short geographical distances and directions in most countries excluding the USA where foot and yard are still widely used for this purpose.
The meter is widely used in most countries and is the official unit for medium lengths and distances (for example, road signs in continental Europe show maximum vehicle hight in meters). Primary exceptions are the United States of America, and some countries where feet and yards are used in limited extent: the United Kingdom and Canada, where the yard remains in limited use as a part of imperial system (for example, yards are used on road signs for shorter distances in the United Kingdom and feet are widely used in construction and real estate in Canada).

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).

1 m is equivalent to 3.28084 ft or 0.000621371 miles.

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 = 1000 millimeters (mm)
  • 1 m = 100 centimeters (cm)
  • 1 m = 10 decimeters (dm)
  • 1 m = 0.001 kilometers (km)
  • 1 m = 3.28084 feet (ft)
  • 1 megameter = 1000000 m
  • 1 gigameter = 1000000000 m
  • Units of length in the metric SI system are based on multiples or fractions of a meter.
  • There are measurements of length/distance in the metric SI system greater than a meter that can be expressed in terms of metres.

1 m is equivalent to 3.28084 ft or 1.09361 yd.

The meter is a unit of length in the metric SI system and is 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).

Meters also can be marked as metres (in British English spelling).

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:

  • Measuring the smoothness or roughness of metal surfaces, such as steel, aluminum and copper.
  • Measuring the flatness or curvature of glass surfaces, such as lenses, mirrors and windows.
  • Measuring the thickness or diameter of thin films, coatings and wires.
  • Measuring the accuracy or tolerance of machined parts, such as gears, bearings and shafts.

The microinch is commonly used in engineering and manufacturing fields, especially in precision machining, metrology and quality control. Some examples are:

  • Measuring the surface finish of machined parts, such as turned, milled and ground surfaces.
  • Measuring the surface profile of textured surfaces, such as honed, lapped and polished surfaces.
  • Measuring the surface geometry of complex surfaces, such as grooved, fluted and serrated surfaces.
  • Measuring the surface defects of defective surfaces, such as scratches, pits and dents.

The microinch is also used for measuring the wavelength of light and other electromagnetic waves. For example:

  • Measuring the color or frequency of visible light, infrared light and ultraviolet light.
  • Measuring the polarization or phase of coherent light, such as laser light and holographic light.
  • Measuring the interference or diffraction patterns of interfering light, such as interferometric light and diffractive light.

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:

  • To convert a microinch to inches, divide by 1,000,000:

1 µin x 25.4 = 25.4 nm

  • To convert an inch to microinches, multiply by 1,000,000:

1 in x 1,000,000 = 1,000,000 µin

  • To convert a foot to microinches, multiply by 12,000,000:
