  3. Microsecond - Wikipedia

    en.wikipedia.org/wiki/Microsecond

    A microsecond is a unit of time in the International System of Units (SI) equal to one millionth (0.000001 or 10 −6 or 1 ⁄ 1,000,000) of a second. Its symbol is μs, sometimes simplified to us when Unicode is not available. A microsecond is to one second, as one second is to approximately 11.57 days.

    The smallest meaningful increment of time is the Planck timeā€•the time light takes to traverse the Planck distance, many decimal orders of magnitude smaller than a second. [ 1 ] The largest realized amount of time, based on known scientific data, is the age of the universe , about 13.8 billion years—the time since the Big Bang as measured in ...

    The angstrom (symbol Å) is a unit of distance used in chemistry and atomic physics equal to 100 pm. The micron (μ) is a unit of distance equal to one micrometre (1 μm). The basic module (M) is a unit of distance equal to one hundred millimetres (100 mm). The myriametre (mym) is a unit of distance equal to ten kilometres (10 km).

  8. Unit of length - Wikipedia

    en.wikipedia.org/wiki/Unit_of_length

    The base unit in the International System of Units (SI) is the meter, defined as "the length of the path travelled by light in vacuum during a time interval of 1 ⁄ 299792458 seconds." [ 9 ] It is approximately equal to 1.0936 yd .

  9. Transmission time - Wikipedia

    en.wikipedia.org/wiki/Transmission_time

    The propagation delay of a physical link can be calculated by dividing the distance (the length of the medium) in meter by its propagation speed in m/s. Propagation time = Distance / propagation speed. Example: Ethernet communication over a UTP copper cable with maximum distance of 100 meter between computer and switching node results in:
