s

Definition

The second (symbol: s) is the SI base unit of time, defined as the duration of 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom.

History/Origin

The second was originally defined as 1/86,400 of a mean solar day. In 1967, it was redefined using atomic time standards based on cesium-133 atomic transitions, providing unprecedented accuracy and stability.

Current Use

Seconds are used universally for all time measurements, from scientific experiments requiring nanosecond precision to everyday timekeeping. Applications include physics experiments, navigation systems, computer operations, and all forms of time measurement.
