Seconds are a unit of time measurement in the International System of Units (SI). They are used to measure very short periods of time, such as in sports timing, cooking, and scientific experiments.
1 second is equal to 1/60 minute or 1/3600 hour. It is also equal to 1000 milliseconds.
Seconds are commonly used in everyday life for timing short activities, such as running races, cooking food, and waiting for traffic lights.
