The millisecond (ms) is a time unit equal to one-thousandth of a second, critical in computing, telecommunications, and scientific experiments where precise timing matters. Network latency, camera shutter speeds, and reaction time measurements all operate on the millisecond scale. One millisecond equals exactly 0.001 seconds, and the human eye can barely perceive changes faster than about 10 milliseconds.

The minute (min) is a time unit equal to 60 seconds, universally used for scheduling, cooking timers, and everyday timekeeping. Meeting durations, exercise intervals, and transportation schedules all rely on minutes as their primary unit. One minute equals exactly 60 seconds, and 60 minutes make up one hour.
