The base SI unit of time. Originally defined as 1/86,400 of a mean solar day, it has been defined since 1967 by the frequency of the hyperfine transition of cesium-133 atoms (9,192,631,770 cycles = 1 second). Universally used and a core time unit in China’s legal metrology system, essential for science, communications, and navigation in all high-precision timing applications.
