How to convert

1 micron (µ) = 0.000001 meter (m). Micron (µ) is a unit of Length used in Metric system. Meter (m) is a unit of Length used in Metric system.

Micron: A Unit of Length

A 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 Micron

To 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:

• 1 inch = 25,400 µm
• 1 foot = 304,800 µm
• 1 mile = 1,609,344,000 µm
• 1 centimeter = 10,000 µm
• 1 meter = 1,000,000 µm
• 1 kilometer = 1,000,000,000 µm

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:

• To convert 50 µm to inches, we divide 50 by 25,400 and get 0.00197 inches.
• To convert 3 feet to microns, we multiply 3 by 304,800 and get 914,400 µm.

Where Micron is Used

The micron is used in various fields and applications that require measuring very small distances or sizes. Some examples are:

• In biology and medicine, the micron is used to measure the size of cells, bacteria, viruses, and other microscopic organisms.
• In engineering and manufacturing, the micron is used to measure the thickness of films, coatings, wires, fibers, and other materials.
• In astronomy and optics, the micron is used to measure the wavelength of infrared light and the resolution of telescopes and cameras.
• In geology and mineralogy, the micron is used to measure the grain size of rocks and minerals.
• In chemistry and physics, the micron is used to measure the diameter of atoms and molecules.

The use of micron varies by country and region. For example:

• In the United States and Canada, the micron is commonly used in engineering and manufacturing industries.
• In Europe and Asia, the micron is widely used in science and technology fields.
• In Australia and New Zealand, the micron is often used in agriculture and forestry sectors.

Definition of the Micron

The 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 ten-millionth 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 Micron

The 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 English-speaking 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 Units

Here are some examples of converting micron to other units of length:

• 1 µm = 0.000001 m
• 1 µm = 0.001 mm
• 1 µm = 0.00003937 inch
• 1 µm = 0.000003281 foot
• 1 µm = 0.000000001 km
• 1 µm = 0.0000006214 mile
• 1 µm = 1000 nm

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).
