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 or /₁₀₀₀) of a second or 1000 microseconds.

A millisecond is to one second, as one second is to approximately 16.67 minutes.

A unit of 10 milliseconds may be called a centisecond, and one of 100 milliseconds a decisecond, but these names are rarely used. To help compare orders of magnitude of different times, this page lists times between 10 seconds and 10 seconds (1 millisecond and one second). See also times of other orders of magnitude.

Horizontal logarithmic scale marked with units of time

Examples

The Apollo Guidance Computer used metric units internally, with centiseconds used for time calculation and measurement.
