A mile is a unit of length, usually used to measure distance, in a number of different systems, including Imperial units, United States customary units and Norwegian/Swedish mil. Length is the long Dimension of any object The length of a thing is the distance between its ends its linear extent as measured from end to end Distance is a numerical description of how far apart objects are Imperial units or the Imperial system is a collection of units first defined in the British Weights and Measures Act of 1824 US customary units, also known in the United States as English units or Imperial units (in reference to the British Empire) (but see English A mil ( Norwegian and Swedish for Mile) is a unit of Length, usually used to measure geographic distance fairly common in Norway Its size can vary from system to system, but in each is between one and ten kilometers. The kilometre ( American spelling: kilometer) symbol km is a unit of Length in the Metric system, equal to one thousand In contemporary English contexts, mile most commonly refers to the international mile of 5,280 feet, 1,760 yards, or exactly 1,609. A foot (plural feet or foot; symbol or abbreviation ft or sometimes &prime – the prime symbol) is a non-SI unit A yard (abbreviation yd) is a unit of Length in several different systems including English units Imperial units and United 344 meters. The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International However it can also refer to either of the following for specific uses:
There have been several abbreviations for mile (with and without trailing period): mi, ml, m, M. In the United States, the National Institute of Standards and Technology now uses and recommends mi but in everyday usage (at least in the United States and in the United Kingdom) usages such as miles per hour and miles per gallon are almost always abbreviated as mph or mpg (rather than mi/h or mi/gal). The United States of America —commonly referred to as the The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located Miles per gallon ( MPG) is a metric term that measures how many miles a vehicle can travel on one gallon of fuel
The formula "multiply by 8 and divide by 5" to convert international miles to kilometers gives a conversion of 1. 6, accurate to 0. 6%, which is a useful approximation.
The unit of distance mille passus (literally "a thousand paces" in Latin, with one pace being equal to two steps) was first used by the Romans and denoted a distance of 1,000 paces or 5,000 Roman feet, and corresponded to about 1,480 meters, or 1,618 modern yards. A pace (or double-pace) is a measure of Distance used in Ancient Rome. Ancient Rome was a Civilization that grew out of a small agricultural community founded on the Italian Peninsula as early as the 10th century BC This unit is now known as the Roman mile. 
The current definition of a mile as 5,280 feet (as opposed to 5,000) dates to the 13th century, and was confirmed by statute in the reign of Queen Elizabeth I; However, various English-speaking countries maintained independent length standards for the yard, which differed by small but measurable amounts, and thus led to miles of slightly different lengths. This was resolved in 1959 with the definition of the current international mile by Australia, Canada, New Zealand, South Africa, the United Kingdom, and the United States.

In modern usage, various distances are referred to as miles.
The international mile (and before 1959, the statute mile) is the distance typically meant when the word mile is used without other qualifying words (e. g. nautical mile, see below). The international and statute miles are both equal to 5,280 feet, but the international mile is defined in terms of the international foot (0. 3048 m), while the statute miles of the various English-speaking countries were based on the national foot of each country. The (mostly obsolete) U. S. statute mile is based on the U. S. survey foot (which is exactly 1200/3937 m) and differs from the international mile by about 3 mm. 
The name statute mile originates from a Statute of the Parliament of England in 1592 during the reign of Elizabeth I. A statute is a formal written enactment of a Legislative authority that governs a Country, State, City, or County. The Parliament of England was the Legislature of the Kingdom of England. This defined the statute mile as 5,280 ft or 1,760 yards; or 63,360 inches. Inches redirects here To see the Les Savy Fav album see Inches. Both statute and international miles are divided into eight furlongs (the length generally that a furrow was ploughed before the horses were turned, furlong = furrow-long). A furlong is a measure of Distance in Imperial units and US customary units. In turn a furlong is ten chains (a surveyor's chain, used as such until laser range finders took over); a chain is 22 yards and a yard is three feet, making up 5,280 ft. A chain is a unit of Length; it measures 66 feet or 22 yards (20
Before the statute of the English parliament, there was confusion on the length of the "mile". The Irish mile was 6,721 feet and the Scottish mile was 5,951 feet.  Perhaps the earliest tables of English linear measures, Arnold's Customs of London (c. 1500) indicates a mile consisted of 8 furlongs, each of 625 feet, for a total of 5,000 feet.  For other "miles" see the list below.
The nautical mile was originally defined as one minute of arc along a meridian (or in some instances any great circle) of the Earth. A nautical mile or sea mile is a unit of Length. It corresponds approximately to one minute of Latitude along any meridian. A minute is a Unit of measurement of Time or of Angle. The minute is a unit of Time equal to 1/60th of an Hour or 60 In Geometry, an arc is a closed segment of a Differentiable Curve in the two-dimensional plane; for example a circular This article is about the geographical concept For other uses of the word see Meridian. A great circle is a Circle on the surface of a Sphere that has the same circumference as the sphere dividing the sphere into two equal Hemispheres.  Although this distance varies depending on the latitude of the meridian (or great circle) where it is used, on average it is about 6,076 feet (about 1852 meters or 1. The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International 15 statute miles). A mile is a unit of Length, usually used to measure Distance, in a number of different systems including Imperial units United States
The nautical mile per hour is known as the knot.
Navigators use dividers to step off the distance between two points on the nautical chart, then place the open dividers against the minutes-of-latitude scale at the edge of the nautical chart, and read off the distance in nautical miles.  Since it is now known that the Earth is an ellipsoid (oblate spheroid), not a sphere, the distance of nautical miles derived from this method varies from the equator to the poles. An oblate Spheroid is a rotationally symmetric Ellipsoid having a polar axis shorter than the diameter of the equatorial circle whose plane For instance, using the WGS84 Ellipsoid, the commonly accepted Earth model for many purposes today, one minute of latitude at the WGS84 equator is 6,087 feet and at the poles is 6,067 feet. The World Geodetic System defines a reference frame for the earth for use in Geodesy and Navigation.
In the United States of America, the nautical mile was defined in the nineteenth century as 6,080. The United States of America —commonly referred to as the 2 feet (1,853. 249 m), whereas in the United Kingdom the Admiralty nautical mile was defined as 6,080 feet (1,853. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located 184 m) and was approximately one minute of latitude in the latitudes of the south of the UK. Other nations had different definitions of the nautical mile, but it is now internationally defined to be exactly 1,852 meters.
The nautical mile is almost universally used for navigation in aviation, maritime, and nautical roles because of its relationship with degrees and minutes of latitude and the ability to use the latitude scale of a map for distance measuring.
Even in countries that have moved from the Imperial to the Metric system (for example, Australia and New Zealand), the mile is still used in a variety of idioms. An idiom is a Phrase whose meaning cannot be deduced from the literal Definition, but refers instead to a figurative meaning that is known only These include:
