A second is a unit of time that is widely used in everyday life. It is the base unit of time in the International System of Units (SI) and is defined as 1/60 of a minute. This means that there are 60 seconds in a minute, and 3,600 seconds in an hour. Seconds are essential for measuring time in various activities, from cooking to sports. Clocks and timers often display time in seconds, helping people keep track of short intervals. The concept of seconds is also important in fields like science and technology, where precise timing is crucial for experiments and processes.
