Although most contemporary accounts used an Arabic mile of 6 444 feet (1,964 metres), which gave a Spanish league of the degree of 25,776 feet (7,857 metres or 4.242 modern nautical miles) others defined an Arabic mile as just 6,000 feet making a Spanish league of the degree 24,000 feet (or 7,315 metres, almost exactly 3.95 modern nautical miles).
Quarter-mile or 1 ⁄ 4 mile may refer to: A dragstrip competition or vehicle test in motorsport, where cars or motorcycles compete for the shortest time from a standing start to the end of a straight 1 ⁄ 4 mile (0.40 km) track; The 440-yard dash, a sprint footrace in track and field competition on a 440 yards (1,320 ft; 400 m; 0.25 mi) oval
On 1 July 1959, the imperial mile was standardized to an exact length in metres. This figure corresponds to 5280 feet at 25.4 millimeters per inch. 1,609.3472 (statute) mile: United States: 1893: 2022: 1,760 yards: From 1959 also called the US Survey Mile. From then, its only utility has been land survey, before it was the standard mile.

[1] [2] In order to make mileposts consistent with the real mileage, every milepost beyond the equation would need to be moved. [3] For example, an equation of 7.6 back = 9.2 ahead means that the feature does not have any section between mile 7.6 and mile 9.2, and the distance between mileposts 7 and 10 is only 1.4 miles. This would usually be ...
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).
The rod, perch, or pole (sometimes also lug) is a surveyor's tool [1] and unit of length of various historical definitions. In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.
Top Fuel (class designation: AA/D top fuel dragster) and Fuel Funny Car (class designation: AA/FC top fuel coupe) have recently been limited to a 1,000-foot (300 m) track, instead of the historic 1/4 mile [1,320 feet (402 m)], as a means to limit top speeds and increase safety (there had been a number of engine explosions at or near 300 mph ...
