Horizontal logarithmic scale marked with units of time

A millisecond (from milli- and second; symbol: ms) is a thousandth (0.001 or 10−3 or 1/1000) of a second.[1][2]

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

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 103 seconds and 100 seconds (1 millisecond and one second). See also times of other orders of magnitude.



For a list half-lives in this timescale, see: List of isotopes by half-life
