    696 ps: How much more a second lasts far away from Earth's gravity due to the effects of General Relativity: 10 −9: nanosecond: ns One billionth of one second 1 ns: The time needed to execute one machine cycle by a 1 GHz microprocessor 1 ns: The time light takes to travel 30 cm (11.811 in) 10 −6: microsecond: μs One millionth of one second

  3. Unit of time - Wikipedia

    en.wikipedia.org/wiki/Unit_of_time

    One trillionth of a second. nanosecond: 10 −9 s: One billionth of a second. Time for molecules to fluoresce. shake: 10 −8 s: 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 ...

  4. Microsecond - Wikipedia

    en.wikipedia.org/wiki/Microsecond

    A microsecond is to one second, as one second is to approximately 11.57 days. A microsecond is equal to 1000 nanoseconds or 1 ⁄ 1,000 of a millisecond. Because the next SI prefix is 1000 times larger, measurements of 10 −5 and 10 −4 seconds are typically expressed as tens or hundreds of microseconds.

  5. Data mile - Wikipedia

    en.wikipedia.org/wiki/Data_mile

    In radar-related subjects and in JTIDS, a data mile is a unit of distance equal to 6,000 feet (1,829 metres; 0.9875 nautical miles; 1.136 miles). An international mile is 0.88 data mile. The speed of light is 299,792,458 metres per second (983,571,056 ft/s), or about one foot per nanosecond .

  6. 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.

  7. Time dilation - Wikipedia

    en.wikipedia.org/wiki/Time_dilation

    Daily time dilation (gain or loss if negative) in microseconds as a function of (circular) orbit radius r = rs/re, where rs is satellite orbit radius and re is the equatorial Earth radius, calculated using the Schwarzschild metric. At r ≈ 1.497 [Note 1] there is no time dilation. Here the effects of motion and reduced gravity cancel.

    Musk claims that cumulative user seconds, specifically via Android and iOS, is the “hardest to game.” A source at the firm said this to me, too. “It’s more exact, it does keep bots out of ...

  9. Radar mile - Wikipedia

    en.wikipedia.org/wiki/Radar_mile

    Radar timing is usually expressed in microseconds. To relate radar timing to distances traveled by radar energy, the speed is used to calculate it. With speed of radar waves at approximately the speed of light in vacuum or 299,792,458 metres per second (300 m/μs; 984 ft/μs) and nautical mile at 1,852 metres (6,076 ft), the delay per nautical ...
