History

Hour (h)

The hour, symbol h, is 60 minutes or 3,600 seconds. It began in ancient times, when people divided the day into 24 parts based on the sun’s movement. This method of dividing the day has remained throughout history. Today, hours organize daily life—jobs, TV, and transport rely on them. The hour is not an SI unit, but it is widely used for convenience and accuracy.

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.
