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.
Microsecond (µs)
The microsecond, symbolized as µs, is one millionth of a second. This very short time is important in electronics, communication, and research. Microseconds are used to measure signal delays, computer speeds, and fast changes. As digital technology grew in the 1900s, measuring microseconds became necessary. Today, this accuracy supports applications such as fast trading, medical imaging, and satellite communications.
