  2. Nautical mile - Wikipedia

    en.wikipedia.org/wiki/Nautical_mile

    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).

  3. League (unit) - Wikipedia

    en.wikipedia.org/wiki/League_(unit)

    From 1630 to 1718 a millia was 5,564 feet (1,696 metres), making a geographical league of four millias equal 22,256 feet (6,784 m or 3.663 modern nautical miles). But from 1718 through the 1830s the millia was defined as the equivalent of just over 5,210 feet, giving a shorter geographical league of just over 20,842 feet (6,353 m or 3.430 ...

  4. 200 metres - Wikipedia

    en.wikipedia.org/wiki/200_metres

    In the United States and elsewhere, athletes previously ran the 220-yard dash (201.168 m) instead of the 200 m (218.723 yards), though the distance is now obsolete. The standard adjustment used for the conversion from times recorded over 220 yards to 200 m times is to subtract 0.1 seconds, [ 1 ] but other conversion methods exist.

  5. Cable length - Wikipedia

    en.wikipedia.org/wiki/Cable_length

    A cable's length (often "cable length" or just "cable") is simply the standard length in which cables came, which by 1555 had settled to around 100 fathoms (600 ft; 180 m) or 1 ⁄ 10 nautical mile (0.19 km; 0.12 mi). [1] Traditionally rope is made on long ropewalks, the length of which determines the maximum length of rope it is possible to make.

  6. Li (unit) - Wikipedia

    en.wikipedia.org/wiki/Li_(unit)

    Li (Chinese: 里, lǐ, or 市里, shìlǐ), also known as the Chinese mile, [citation needed] is a traditional Chinese unit of distance. The li has varied considerably over time but was usually about one third of an English mile and now has a standardized length of a half- kilometer (500 meters or 1,640 feet or 0.311 miles ).

  7. Mile - Wikipedia

    en.wikipedia.org/wiki/Mile

    The Dutch kleine mile had the historical definition of one hour's walking (uur gaans), which was defined as 24 stadia, 3000 paces, or 15,000 Amsterdam or Rhineland feet (respectively 4,250 m or 4,710 m). The common Dutch mile was 32 stadia, 4,000 paces, or 20,000 feet (5,660 m or 6,280 m). The large mile was defined as 5000 paces. [41]

  8. Kármán line - Wikipedia

    en.wikipedia.org/wiki/Kármán_line

    Kincheloe flew 2000 miles per hour (3,200 km/h) at 126,000 feet (38,500 m), or 24 miles up. At this altitude and speed, aerodynamic lift still carries 98 percent of the weight of the plane, and only two percent is carried by inertia, or Kepler force, as space scientists call it. But at 300,000 feet (91,440 m) or 57 miles up, this relationship ...

  9. Twenty Thousand Leagues Under the Seas - Wikipedia

    en.wikipedia.org/wiki/Twenty_Thousand_Leagues...

    The title refers to the distance travelled under the various seas: 20,000 metric leagues (80,000 km, over 40,000 nautical miles), nearly twice the circumference of the Earth. [ 6 ] Principal characters
