Seconds (s)
Definition
A second (s) is the SI base unit of time. Since 1967, it has been defined as the duration of 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the cesium-133 atom.
History
The second was historically defined as 1/86,400 of a mean solar day. Ancient Babylonians used a base-60 system to divide time, leading to 60 seconds in a minute. The modern atomic definition was adopted in 1967 for unparalleled precision.
Current use
The second is the fundamental time unit used in all scientific, engineering, and everyday applications. It underpins GPS timing, internet synchronization, physics experiments, and is the basis for all derived time units.
Years (avg)
Definition
A year is a unit of time approximately equal to 365.25 days (or 31,557,600 seconds). It corresponds to one complete orbit of the Earth around the Sun.
History
The year has been observed since prehistoric times through seasonal changes. The Julian calendar (45 BC) introduced the 365.25-day average with leap years. The Gregorian calendar (1582) refined this to 365.2425 days, which remains the civil standard.
Current use
Years are the standard unit for age, historical dating, long-term planning, academic calendars, interest rates, climate data, and demographic statistics. Fiscal years, model years, and vintage designations all rely on this unit.
