Millisecond

A millisecond (from milli- and second; symbol: ms) is a unit of time in the International System of Units equal to one thousandth (0.001 or 10⁻³ or ¹/₁₀₀₀) of a second^[1]^[2] and to 1000 microseconds.

A unit of 10 milliseconds may be called a centisecond, and one of 100 milliseconds a decisecond, but these names are rarely used.^[3] 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.
