Years

The year is based on Earth's orbital period around the Sun. The Julian year used in astronomy is exactly 365.25 days (31,557,600 seconds). The Gregorian calendar approximates the tropical year as 365.2425 days through its leap year rule, achieving accuracy to within 26 seconds per year. In geology, time spans are expressed in millions of years (Ma) or billions of years (Ga).

Nanoseconds

The nanosecond is a unit of time equal to one billionth of a second (10⁻⁹ s) and is the operational timescale of modern digital electronics. A 3 GHz processor executes approximately one clock cycle every 0.33 nanoseconds. The propagation of electrical signals through circuits, memory access times, and network packet transmission are all measured in nanoseconds. Light travels approximately 30 cm in one nanosecond.
