    10 microseconds (μs) – cycle time for frequency 100 kHz, radio wavelength 3 km. 18 microseconds – net amount per year that the length of the day lengthens, largely due to tidal acceleration. [3] 20.8 microseconds – sampling interval for digital audio with 48,000 samples/s. 22.7 microseconds – sampling interval for CD audio (44,100 ...

  5. Nanosecond - Wikipedia

    en.wikipedia.org/wiki/Nanosecond

    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. Bit time - Wikipedia

    en.wikipedia.org/wiki/Bit_time

    To calculate the bit time for a 10 Mbit/s NIC, use the formula as follows: bit time = 1 / (10 * 10^6) = 10^-7 = 100 * 10^-9 = 100 nanoseconds The bit time for a 10 Mbit/s NIC is 100 nanoseconds. That is, a 10 Mbit/s NIC can eject 1 bit every 0.1 microsecond (100 nanoseconds = 0.1 microseconds).

  7. Millisecond - Wikipedia

    en.wikipedia.org/wiki/Millisecond

    A millisecond (from milli-and second; symbol: ms) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10 −3 or 1 / 1000) of a second [1] [2] or 1000 microseconds. A millisecond is to one second, as one second is to approximately 16.67 minutes.

  8. Metric time - Wikipedia

    en.wikipedia.org/wiki/Metric_time

    Metric time is the measure of time intervals using the metric system.The modern SI system defines the second as the base unit of time, and forms multiples and submultiples with metric prefixes such as kiloseconds and milliseconds.

  9. Atomic clock - Wikipedia

    en.wikipedia.org/wiki/Atomic_clock

    The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the caesium frequency, , the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s −1.
