A millisecond (from milli- and second; abbreviation: ms) is a thousandth (1/1,000) of a second.[1] Its symbol is ms. One millisecond is to one second as one second is to 16.67 minutes.
10 milliseconds (a hundredth of a second) are called a centisecond, commonly seen on many stopwatches but often mistaken for milliseconds.
100 milliseconds (one tenth of a second) are called a decisecond.
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.
