  2. Nanosecond - Wikipedia

    en.wikipedia.org/wiki/Nanosecond

    1.0 nanosecond – cycle time of an electromagnetic wave with a frequency of 1 GHz (10 9 hertz). 1.0 nanosecond – electromagnetic wavelength of 1 light-nanosecond. Equivalent to 0.3 m radio band. 1.016 703 362 164 nanoseconds (by definition) – time taken by light to travel 1 foot in vacuum. [n 1] 3.335 640 951 9815 nanoseconds (by ...

  4. Unit of time - Wikipedia

    en.wikipedia.org/wiki/Unit_of_time

    10 nanoseconds, also a casual term for a short period of time. microsecond: 10 −6 s: One millionth of a second. Symbol is μs millisecond: 10 −3 s: One thousandth of a second. Shortest time unit used on stopwatches. jiffy (electronics) ~ 10 −3 s: Used to measure the time between alternating power cycles. Also a casual term for a short ...

  5. Nano- - Wikipedia

    en.wikipedia.org/wiki/Nano-

    A nanosecond (ns) is a unit of time in the International System of Units (SI) equal to one billionth of a second, that is, ⁠ 1 / 1 000 000 000 ⁠ of a second, or 10 −9 seconds. The term combines the SI prefix nano- indicating a 1 billionth submultiple of an SI unit (e.g. nanogram, nanometre , etc.) and second , the primary unit of time in ...

  6. List of unusual units of measurement - Wikipedia

    en.wikipedia.org/wiki/List_of_unusual_units_of...

    While usually sub-second units are represented with SI prefixes on the second (e.g. milliseconds), this system can be extrapolated further, such that a "Third" would mean 1 ⁄ 60 of a second (16.7 milliseconds), and a "Fourth" would mean 1 ⁄ 60 of a third (278 microseconds), etc. These units are occasionally used in astronomy to denote angles.

  7. Propagation delay - Wikipedia

    en.wikipedia.org/wiki/Propagation_delay

    An electromagnetic wave travelling through a medium has a propagation delay determined by the speed of light in that particular medium, or ca. 1 nanosecond per 29.98 centimetres (11.80 in) in a vacuum. An electric signal travelling through a wire has an propagation delay of ca. 1 nanosecond per 15 centimetres (5.9 in). [1]

  8. Jiffy (time) - Wikipedia

    en.wikipedia.org/wiki/Jiffy_(time)

    Jiffy values for various Linux versions and platforms have typically varied between about 1 ms and 10 ms, with 10 ms (1/100 s) reported as an increasingly common standard in the Jargon File. [ 11 ] Stratus VOS (Virtual Operating System) uses a jiffy of 1/65,536 second to express date and time (number of jiffies elapsed since 1 January 1980 00: ...

  9. Shake (unit) - Wikipedia

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

    For nuclear-bomb designers, the term was a convenient name for the short interval, rounded to 10 nanoseconds, which was frequently seen in their measurements and calculations: The typical time required for one step in a chain reaction (i.e. the typical time for each neutron to cause a fission event, which releases more neutrons) is of the order of 1 shake, and a chain reaction is typically ...
