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]
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).
Legua nautica (nautical league): Between 1400 and 1600 the Spanish nautical league was equal to four Roman miles of 4,842 feet, making it 19,368 feet (5,903 metres or 3.1876 modern nautical miles). However, the accepted number of Spanish nautical leagues to a degree varied between 14 1/6 to 16 2/3, so in actual practice the length of a Spanish ...
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]
According to this calculation, one mile is equal to $0.01. Likewise, if you spend $2,000 in purchases every month, you earn 48,000 Venture miles or 30,000 VentureOne miles. The former is equal to ...
When each equatorial degree was divided into 18 leagues, the geographical mile was equal to 1 / 54 degree or about 2.06 kilometres (1.28 mi); when divided into 20 leagues, the geographical mile was equal to 1 / 60 degree, approximating the values provided above; and when divided into 25 leagues, the geographical mile was equal ...
vehicle-kilometre (vkm [1]) as a measure of traffic flow, determined by multiplying the number of vehicles on a given road or traffic network by the average length of their trips measured in kilometres. [2] vehicle-mile (vehicle miles traveled, or VMT [1]) same as before but measures the trip expressed in miles.
