In the United States, the term statute mile formally refers to the survey mile, [3] but for most purposes, the difference of less than 1 ⁄ 8 inch (3.2 mm) between the survey mile and the international mile (1609.344 metres exactly) is insignificant—one international mile is 0.999 998 US survey miles—so statute mile can be used for either.

The mile run (1,760 yards, [2] 5,280 feet, or exactly 1,609.344 metres) is a middle-distance foot race.. The history of the mile run event began in England, where it was used as a distance for gambling races.
Respectively, these square divisions of land are approximately 80 chains (one mile or 1.6 km), 40 chains (half a mile or 800 m), and 20 chains (a quarter mile or 400 m) on a side. The chain is still used in agriculture: measuring wheels with a circumference of 0.1 chain (diameter ≈ 2.1 ft or 64 cm) are still readily available in Canada and ...

A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).
Often, the exits are numbered according to the nearest milepost, known as the mile-log system. From the beginning of the Interstate system until the mid-2000s, most Interstate highways had markers every mile. Since that time, many states have installed more markers every 0.25 mile, every 0.2 mile, or in some metro areas, every 0.1 mile.
