It is commonly represented with symbol µs.
One one-thousandth of a second. Symbol: ms.
one millionth of a second; one thousandth of a millisecond

A microsecond is an SI unit of time 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 millisecond (from milli- and second; symbol: ms) is a thousandth (0.001 or 10−3 or 1/1000) of a second.A unit of 10 milliseconds may be called a centisecond, and one of 100 milliseconds a decisecond, but these names are rarely used. Decisecond equals 1/10 of a second Centisecond equals 1/100 of a second Millisecond equals 1/1000 of a second To help compare orders of magnitude of different times, this page lists times between 10−3 seconds and 100 seconds (1 millisecond and one second).
