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.

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

There are 86400000 (24×60×60×10×10×10) milliseconds in one day.

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.
