A microsecond is an SI unit of time equal to one millionth (0.000001 or 10â6 or 1/1,000,000) of a second. Its symbol is Î¼s. One microsecond is to one second as one second is to 11.574 days. A microsecond is equal to 1000 nanoseconds or 1/1,000 milliseconds. Because the next SI prefix is 1000 times larger, measurements of 10â5 and 10â4 seconds are typically expressed as tens or hundreds of microseconds.
