Its symbol is \u03bcs, sometimes simplified to us when Unicode is not available.  A microsecond is equal to 1000 nanoseconds or 1\u20441,000 of a millisecond. Because the next SI prefix is 1000 times larger, measurements of 10\u22125 and 10\u22124 seconds are typically expressed as tens or hundreds of microseconds.Table of ContentsExamples[edit]See also[edit]References[edit]External links[edit]Examples[edit]1 microsecond (1 \u03bcs) \u2013 cycle time for frequency 1\u00d7106\u00a0hertz (1\u00a0MHz), the inverse unit.
