Millisecond


Millisecond
Horizontal logarithmic scale marked with units of time

A millisecond (from milli- and second; abbreviation: ms) is a thousandth (1/1,000) of a second.[1]

10 milliseconds (a hundredth of a second) are called a centisecond.

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.
