A millisecond (from milli- and second; abbreviation: ms) is a thousandth (10−3 or 1/1,000) of a second. Its symbol is ms.

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). See also times of other orders of magnitude...
