Definition of Second

Definition

s — The second is the SI base unit of time. Since 1967, it has been defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom.

The second is the only SI base unit with a prefix-ready name. It forms the basis for all other time measurements in the International System of Units, and is fundamental to definitions of the meter (via the speed of light) and the ampere.
