  2. Microsecond - Wikipedia

    en.wikipedia.org/wiki/Microsecond

    The average human finger snap takes 150,000 microseconds (just over 1 ⁄ 7 second). A camera flash illuminates for 1,000 microseconds. Standard camera shutter speed opens the shutter for 4,000 microseconds or 4 milliseconds. 584542 years of microseconds fit in 64 bits: (2**64)/(1e6*60*60*24*365.25).

  3. 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.

  6. 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.

  7. Decimal time - Wikipedia

    en.wikipedia.org/wiki/Decimal_time

    It is also the standard single-unit time representation in many programming languages, most notably C, and part of UNIX/POSIX standards used by Linux, Mac OS X, etc.; to convert fractional days to fractional seconds, multiply the number by 86400. Fractional seconds are represented as milliseconds (ms), microseconds (μs) or nanoseconds (ns ...

  8. Pulse-per-second signal - Wikipedia

    en.wikipedia.org/wiki/Pulse-per-second_signal

    PPS signals have an accuracy ranging from 12 picoseconds to a few microseconds per second, or 2.0 nanoseconds to a few milliseconds per day based on the resolution and accuracy of the device generating the signal.

  9. Nanosecond - Wikipedia

    en.wikipedia.org/wiki/Nanosecond

    A nanosecond is equal to 1000 picoseconds or ⁠ 1 / 1000 ⁠ microsecond. Time units ranging between 10 −8 and 10 −7 seconds are typically expressed as tens or hundreds of nanoseconds. Time units of this granularity are commonly found in telecommunications, pulsed lasers, and related aspects of electronics.
