There are two common pronunciations for the word. [1]/ ˈ k ɪ l ə m iː t ər,-l oʊ-/ / k ɪ ˈ l ɒ m ɪ t ər / The first pronunciation follows a pattern in English whereby SI units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre ...
The statsiemens or statmho is a unit of electric conductance equal to 1 statA/statV, corresponding to ~ 1.112 646 pS. [6] The stathenry is a unit of electric inductance equal to 1 statV·s/statA, corresponding to ~ 898.755 1787 GH. [7] [6] [a] The statfarad (statF) is a unit of electric capacitance equal to 1 statC/statV, corresponding to ~ 1. ...
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.
1.280 km – span of the Golden Gate Bridge (distance between towers) [139] 1.609 km – 1 statute mile; 1.852 km – 1 nautical mile, equal to 1 arcminute of latitude at the surface of the Earth [140] 1.991 km – span of the Akashi Kaikyō Bridge [141] 2.309 km – axial length of the Three Gorges Dam, the largest dam in the world located in ...
This definition fixed the speed of light in vacuum at exactly 299 792 458 metres per second [122] (≈ 300 000 km/s or ≈1.079 billion km/hour [124]). An intended by-product of the 17th CGPM's definition was that it enabled scientists to compare lasers accurately using frequency, resulting in wavelengths with one-fifth the uncertainty involved ...
To keep an eye-safe environment, good FSO systems have a limited laser power density and support laser classes 1 or 1M. Atmospheric and fog attenuation, which are exponential in nature, limit practical range of FSO devices to several kilometers.
The benz, named in honour of Karl Benz, has been proposed as a name for one metre per second. [10] Although it has seen some support as a practical unit, [11] primarily from German sources, [10] it was rejected as the SI unit of velocity [12] and has not seen widespread use or acceptance.
In the context of ocean currents, a volume of one million cubic meters may be imagined as a "slice" of ocean with dimensions 1 km × 1 km × 1 m (width × length × thickness). At this scale, these units can be more easily compared in terms of width of the current (several km), depth (hundreds of meters), and current speed (as meters per second).
