Milliseconds

The millisecond is a unit of time equal to one thousandth of a second (10⁻³ s) and represents the timescale of human physiological responses and digital audio. The human minimum reaction time to a visual stimulus is approximately 150–200 milliseconds. Network latency in internet communications is measured in milliseconds, where values below 20 ms are considered excellent for real-time applications.

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).
