Furlong: A Unit of Length Used in the US Customary System
The furlong (fur) is a unit of length in the US customary system, which is one of the systems of measurement used in the United States and some other countries. The furlong is equal to 220 yards, which is an eighth of a mile. The furlong is also a derived unit in the imperial system, which is the official system of measurement for the United Kingdom and some other Commonwealth countries. The symbol for furlong is fur. The furlong is used for measuring long distances and areas, such as the length of a horse race or the area of a farm. The furlong is named after the furrow-long, which was the length of a furrow in one acre of a plowed open field in medieval England. In this article, we will explore the definition, history, usage and conversion of the furlong as a unit of length.
Definition of the Unit
The furlong is a unit of length that is equal to 220 yards. It is defined as 1/8 miles. The mile is defined as 5,280 feet or 1,760 yards.
The definition of the furlong has not changed since its origin in medieval England, as part of the old English system of measurement that was based on natural and traditional units. However, the definition of the mile has changed several times 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 feet and yards was agreed upon by an international treaty in 1959.
History of the Unit
The origin of the furlong as a unit of length can be traced back to medieval England, when it was used as a measure of land area and distance. The word furlong comes from the Old English words furh (furrow) and lang (long), meaning furrow-long. It referred to the length of a furrow in one acre of a plowed open field, which was a common system of land division and cultivation at that time. The open field was divided into strips or selions, each strip being one furlong long and one rod wide. A rod was equal to 5.5 yards or 16.5 feet. An acre was equal to four rods by 40 rods, or 160 square rods.
The furlong was also used as a measure of distance for horse racing and other sports. The standard length of a horse race was four furlongs, or half a mile. This was later increased to eight furlongs, or one mile, which became known as the classic distance for horse racing.
The furlong 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, 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 furlong 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 Unit
The furlong is a unit of length that is used for measuring long distances and areas, such as the length of a horse race or the area of a farm.
The furlong is commonly used in horse racing, especially in North America and some other countries that follow the US customary system. Some examples are:
The furlong is also used in agriculture, especially in rural areas where farms are still measured by acres and furlongs. Some examples are:
How to Convert
The furlong can be converted to other units of length by using conversion factors or formulas. Here are some examples of how to convert furlongs to other units of length in the US customary system, the SI system and other systems:
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:
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 Used
The 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 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.
