  2. Millisecond - Wikipedia

    en.wikipedia.org/wiki/Millisecond

    A millisecond is to one second, as one second is to approximately 16.67 minutes. A unit of 10 milliseconds may be called a centisecond , and one of 100 milliseconds a decisecond , but these names are rarely used. [ 3 ]

  4. Metric time - Wikipedia

    en.wikipedia.org/wiki/Metric_time

    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. Other units of time – minute , hour , and day – are accepted for use with SI , but are not part of it.

  5. Orders of magnitude (time) - Wikipedia

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

    Clock time and calendar time have duodecimal or sexagesimal orders of magnitude rather than decimal, e.g., a year is 12 months, and a minute is 60 seconds. The smallest meaningful increment of time is the Planck time ―the time light takes to traverse the Planck distance , many decimal orders of magnitude smaller than a second.

  6. Time perception - Wikipedia

    en.wikipedia.org/wiki/Time_perception

    Sub-second timing or millisecond timing; Interval timing or seconds-to-minutes timing; Circadian timing; There are many theories and computational models for time perception mechanisms in the brain. William J. Friedman (1993) contrasted two theories of the sense of time: [6] [7] [8] The strength model of time memory.

  7. Light-second - Wikipedia

    en.wikipedia.org/wiki/Light-second

    A light-minute is 60 light-seconds, and so the average distance between Earth and the Sun is 8.317 light-minutes. The average distance between Pluto and the Sun (34.72 AU [5]) is 4.81 light-hours. [6] Humanity's most distant artificial object, Voyager 1, has an interstellar velocity of 3.57 AU per year, [7] or 29.7 light-minutes per year. [8]

    en.wikipedia.org/wiki/List_of_humorous_units_of...

    In the Zork series of games, the Great Underground Empire has its own system of measurements, the most frequently referenced of which is the bloit. Defined as the distance the king's favorite pet can run in one hour (spoofing a popular legend about the history of the foot), the length of the bloit varies dramatically, but the one canonical conversion to real-world units puts it at ...
