Definition of microsecond in US English:


(also μs)


  • One millionth of a second.

    • ‘Smaller units of time are measured in milliseconds which are one thousandth of a second and microseconds, which are one millionth of a second.’
    • ‘Whether the making of Adam prior to creation of the soul lasted a microsecond or a million years, is not certain from the Torah.’
    • ‘However, this tends to be practical only when required response times are in milliseconds - not microseconds.’
    • ‘The deadlines themselves are application-dependent and can vary from tens of microseconds up to several seconds.’
    • ‘In their measurements the authors recorded the dynamics of the photocycle and reconstructed it as a sum of nine exponents that vary in their half-life times from a microsecond up to tens of milliseconds.’
    • ‘That is why when you've seen one electron you've seen them all, that is why bits of copper all behave like bits of copper, and that is why each electron and each bit of copper stays the same as itself from microsecond to microsecond.’
    • ‘Most people can't tell the difference between milliseconds and microseconds in the throughput specs and, anyway, with chip prices so low, cache is king.’
    • ‘Second, no fusion event has been observed with a fusion time between 350 nanoseconds and 2 microseconds.’
    • ‘The phases are well separated in time spanning hundreds of nanoseconds to hundreds of microseconds and the amplitudes contribute more or less equally to the total decay, the slowest phase contributing the least.’
    • ‘The primary motivation behind installing an SSD is its ability to access data in microseconds instead of milliseconds (as with rotational disks).’
    • ‘That shift of mass would increase the length of day by only 0.06 microseconds and make the Earth only very slightly more round in the middle and flat on the top.’
    • ‘The triplet excited state of dyes bound to DNA can serve as probes of slow motions of DNA molecules on timescales of microseconds to milliseconds.’
    • ‘The combined effect of the lunar and solar tidal torques is to increase the length of the day by 24 microseconds each year.’
    • ‘He began to dwell for a microsecond on the pain he felt that day and the hole that had formed after the first building collapsed.’
    • ‘The technology revolves around neural network processors which can solve very complex problems in real time, where real time is microseconds rather than milliseconds.’
    • ‘A single photon wavelength measurement can be completed in a fraction of a microsecond, but the accuracy will be many orders of magnitude less.’
    • ‘This amount of time, so long when measured against our lives, is a geological microsecond.’
    • ‘The two measured periods differed by 27 microseconds.’
    • ‘The theory presented here is aimed at bridging the gap between microseconds and hours.’
    • ‘The initial collapse is followed by two fast (tens of microseconds and hundreds of nanoseconds) reorganizational phases in which the intermediates sample their environment searching for appropriate native contacts.’
