Convert Micrometers to Miles (µm to mi) ▶
How to convert
1 mile (mi) = 1609344000 micrometer (µm). Mile (mi) is a unit of Length used in Standard system. Micrometer (µm) is a unit of Length used in Metric system.
Mile: A Unit of Length
The mile is a unit of length that is equal to 5,280 feet or 1,760 yards. It is based on the older English unit of length that was used before the adoption of the metric system. The mile is also a derived unit in the British imperial and US customary systems of measurement. The symbol for mile is mi or m.
The mile is most commonly used when expressing distances on land or in air travel. The mile is also used for measuring speed, such as miles per hour (mph). The mile is sometimes distinguished from other types of miles, such as the nautical mile or the geographical mile, by using the term statute mile.
In this article, we will explore the definition, history, usage and conversion of the mile as a unit of length.
Definition of the Mile
The mile is a unit of length that is equal to 5,280 feet or 1,760 yards. It is defined as 1,609.344 meters by international agreement in 1959. One foot is equal to 0.3048 meter and one yard is equal to 0.9144 meter.
The definition of the mile has changed over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the mile as based on the meter was agreed upon by an international treaty in 1959.
History of the Mile
The origin of the mile as a unit of length can be traced back to ancient times, when it was used as a measure of distance based on the human pace. The word mile comes from the Latin word mille, which means thousand. It referred to the distance of one thousand paces, which was about 5,000 Roman feet or 1.48 kilometers.
The mile was adopted by other countries that followed the Roman system of measurement, such as England and France. It varied in length from country to country and from time to time, depending on local standards and methods of measurement.
The mile was standardized in England by an act of Parliament in 1593, which set it as a distance of 8 furlongs or 5,280 feet. A furlong was a measure of distance used for plowing fields and was equal to 660 feet or 40 rods. A rod was a measure of length used for surveying land and was equal to 16.5 feet or 5.5 yards.
The mile was adopted by other countries that followed the English system of measurement, such as the United States and Canada. It was also incorporated into the imperial system of measurement, which was established by an act of Parliament in 1824. The imperial system was based on seven base units that could be derived from natural and traditional units. The mile remained as a derived unit in the imperial system, but it was no longer recommended for use in scientific and technical fields.
Usage of the Mile
The mile is a unit of length that is used for measuring distances on land or in air travel. For example:
The mile is commonly used in everyday life, especially in countries that follow the British imperial or US customary systems of measurement. Some examples are:
The mile is also used for measuring speed, such as miles per hour (mph). This is a measure of how fast an object moves in relation to another object or point. For example:
Example Conversions of Mile to Other Units
The mile 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 mi x 5,280 = 5,280 ft
1 mi x 1,760 = 1,760 yd
1 mi x 1,609.344 = 1,609.344 m
1 mi x 1.609344 = 1.609344 km
1 mi / 1.150779 = 0.868976 nmi
1 mi / 0.869 = 1.151 mi
1 ft / 5,280 = 0.000189 mi
1 yd / 1,760 = 0.000568 mi
1 m / 1,609.344 = 0.000621 mi
1 km / 1.609344 = 0.621371 mi
1 nmi x 1.150779 = 1.150779 mi
1 mi x 0.869 = 0.869 mi
Micrometer: A Unit of Length
Definition of the micrometer
The 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 micrometer
The 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 micrometer
The 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 used
The 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:
