The "old English mile" of the medieval and early modern periods varied but seems to have measured about 1.3 international miles (2.1 km). [17] [18] The old English mile varied over time and location within England. [18] The old English mile has also been defined as 79,200 or 79,320 inches (1.25 or 1.2519 statute miles). [19]
1,760 yards: On 1 July 1959, the imperial mile was standardized to an exact length in metres 1,609.3472 (statute) mile: United States: 1893: today: 1,760 yards: From 1959; also called the U.S. Survey Mile. From then its only utility has been land survey, before it was the standard mile. From 1893 its exact length in metres was: 3,600 / ...
The yard (symbol: yd) [3] [4] is an English unit of length in both the British imperial and US customary systems of measurement equalling 3 feet or 36 inches. Since 1959 it has been by international agreement standardized as exactly 0.9144 meter. A distance of 1,760 yards is equal to 1 mile. The US survey yard is very slightly longer.
The most commonly used units are the mile or "li" (哩, li 1), the yard or "ma" (碼, maa 5), the foot or "chek" (呎, cek 3), and the inch or "tsun" (吋, cyun 3). The traditional measure of flat area is the square foot ( 方呎, 平方呎 , fong 1 cek 3 , ping 4 fong 1 cek 3 ) of the imperial system, which is still in common use for real ...
The chain (abbreviated ch) is a unit of length equal to 66 feet (22 yards), used in both the US customary and Imperial unit systems. It is subdivided into 100 links. [1] [2] There are 10 chains in a furlong, and 80 chains in one statute mile. [2] In metric terms, it is 20.1168 m long. [2]
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.
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).
[citation needed] In Argentina, the vara measured about 866 mm (34.1 in), and typical urban lots are 8.66 m (28.41 ft) wide (10 Argentine varas). At some time a value of 33 inches (838.2 mm) was adopted in California. [citation needed] In Texas, a vara was defined as 33 + 1 ⁄ 3 inches (846.67 mm), or 1 yard = 1.08 vara.
