  3. Microsecond - Wikipedia

    en.wikipedia.org/wiki/Microsecond

    1 microsecond – protein folding takes place on the order of microseconds (thus this is the speed of carbon-based life). 1.8 microseconds – the amount of time subtracted from the Earth's day as a result of the 2011 Japanese earthquake. [1] 2 microseconds – the lifetime of a muonium particle.

    1 millisecond – time taken for light to travel 204.19 km in a single mode fiber optic cable for a wavelength of 1550 nm (frequency: 193 THz). 1 millisecond – nerve conduction velocity (neuron signal firing) happens on the order of milliseconds; 1.000692286 milliseconds – time taken for light to travel 300 km in a vacuum

  6. Metric time - Wikipedia

    en.wikipedia.org/wiki/Metric_time

    The commission rejected the seconds-pendulum definition of the metre the following year because the second of time was an arbitrary period equal to 1/86,400 day, rather than a decimal fraction of a natural unit. Instead, the metre would be defined as a decimal fraction of the length of the Paris Meridian between the equator and the North Pole.

  8. Transmission time - Wikipedia

    en.wikipedia.org/wiki/Transmission_time

    The packet transmission time in seconds can be obtained from the packet size in bit and the bit rate in bit/s as: Packet transmission time = Packet size / Bit rate. Example: Assuming 100 Mbit/s Ethernet, and the maximum packet size of 1526 bytes, results in Maximum packet transmission time = 1526×8 bit / (100 × 10 6 bit/s) ≈ 122 μs

  9. 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.
