Millisecond (ms)
The millisecond, symbol ms, is one-thousandth of a second. It is important to time very short periods. The millisecond, a unit of measurement in the metric system, is used in science, computers, and engineering. It measures speeds and response times in digital devices. People’s reaction times are often measured in milliseconds, making it useful in medicine, sports, and psychology. Its accuracy helps capture events that happen too fast for the eye to see.
Minute (min)
The minute, symbol min, is 60 seconds. Its name comes from the Latin for “first small part.” Minutes have been used since ancient times when base-60 number systems shaped early timekeeping. Minutes are part of daily life—used in clocks, plans, and math. Although the SI system uses seconds, minutes are still important for daily and cultural needs, thereby linking science with everyday life.
