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

    It is an ancient Indian subcontinental standard unit of distance, in use since at least 4 BCE. According to the Arthashastra, a krośa or kos is about 3,000 metres (9,800 ft). [1] Another conversion is based on the Mughal emperor Akbar, who standardized the unit to 5000 guz in the Ain-i-Akbari.

    = ⁡ (where distance and wavelength are in the same units) When substituted into the link budget equation above, the result is the logarithmic form of the Friis transmission equation . In some cases, it is convenient to consider the loss due to distance and wavelength separately, but in that case, it is important to keep track of which units ...

    The kos (kosh, krosh, koss) is a very ancient measure of distance, measuring about 2.25 miles or 3.7 km. [2] 1 angul = approx. 0.75 inch; 4 angul = 1 dharnugrah (bow grip) = 3 in; 8 angul = 1 dhanurmushti (fist with thumb raised) = 6 in; 12 angul = 1 vitastaa = 9 in; 2 vitastaa = 18 in; 1 haath = 1.5 ft. 1 dand or dhanush (bow) = 4 haath = 6 ft

  6. Geographical distance - Wikipedia

    en.wikipedia.org/wiki/Geographical_distance

    Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude. This distance is an element in solving the second (inverse) geodetic ...

    kilometre (km) or kilometer is a metric unit used, outside the US, to measure the length of a journey; the international statute mile (mi) is used in the US; 1 mi = 1.609344 km; nautical mile is rarely used to derive units of transportation quantity.

  8. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    Based on wind resistance, for example, the terminal velocity of a skydiver in a belly-to-earth (i.e., face down) free-fall position is about 195 km/h (122 mph or 54 m/s). [3] This velocity is the asymptotic limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the ...

    The destinations listed can range from a short distance away, such as a few miles or kilometers, to long distances away, from several hundred or even thousands of miles or kilometers away. Unlike most road signs, mileage signs remain roughly consistent throughout the world, with the only differences being background colors on signs and the ...
