    30 nanoseconds – half-life of carbon-21; 77 nanoseconds – a sixth (a 60th of a 60th of a 60th of a 60th of a second) 100 nanoseconds – cycle time for frequency 10 MHz, radio wavelength 30 m ; 294.4 nanoseconds – half-life of polonium-212 [4] 333 nanoseconds – cycle time of highest medium wave radio frequency, 3 MHz

  3. 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 ...

  4. Nano- - Wikipedia

    en.wikipedia.org/wiki/Nano-

    Nano (symbol n) is a unit prefix meaning one billionth.Used primarily with the metric system, this prefix denotes a factor of 10 −9 or 0.000 000 001.It is frequently encountered in science and electronics for prefixing units of time and length.

  5. List of unusual units of measurement - Wikipedia

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

    Valve's Source game engine uses the Hammer unit as its base unit of length. This unit refers to Source's official map creation software, Hammer. [1] The exact definition varies from game to game, but a Hammer unit is usually defined as a sixteenth of a foot (16 Hammer units = 1 foot).

  7. CAS latency - Wikipedia

    en.wikipedia.org/wiki/CAS_latency

    Column address strobe latency, also called CAS latency or CL, is the delay in clock cycles between the READ command and the moment data is available. [1] [2] In asynchronous DRAM, the interval is specified in nanoseconds (absolute time). [3]

  8. Orders of magnitude (time) - Wikipedia

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

    An order of magnitude of time is usually a decimal prefix or decimal order-of-magnitude quantity together with a base unit of time, like a microsecond or a million years.In some cases, the order of magnitude may be implied (usually 1), like a "second" or "year".

  9. Epoch (computing) - Wikipedia

    en.wikipedia.org/wiki/Epoch_(computing)

    Software timekeeping systems vary widely in the resolution of time measurement; some systems may use time units as large as a day, while others may use nanoseconds.For example, for an epoch date of midnight UTC (00:00) on 1 January 1900, and a time unit of a second, the time of the midnight (24:00) between 1 January 1900 and 2 January 1900 is represented by the number 86400, the number of ...
