Minutes to Milliseconds

About Minutes and Milliseconds

Minutes (min): Sixty seconds; comes from the Latin pars minuta prima, 'first small part' (of an hour), with the second coming from pars minuta secunda, the second small part. Common uses: Cooking times, exercise intervals, scheduling, transit timetables, and most everyday time intervals between seconds and hours.

Milliseconds (ms): One thousandth of a second, where the second has been the SI base unit of time since 1967, defined by atomic transitions in cesium-133. Common uses: Computer timing (web page load times, audio sampling, video frames), reaction-time studies, and high-speed photography.

How the conversion works

Time uses fixed SI seconds. A day is exactly 86,400 seconds; a year (Julian) is 365.25 days = 31,557,600 seconds.

The exact relationship is milliseconds = minutes × 60000, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.

When this conversion matters

Converting between minutes and milliseconds comes up wherever time measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
