About These Units
Year (yr)
A year (yr) equals approximately 365.25 days (accounting for leap years) or 8,760 hours. Years measure age, anniversaries, academic periods, and historical timelines. Earth completes one orbit around the Sun in one year. A fiscal year may differ from a calendar year.
Millisecond (ms)
A millisecond (ms) is one thousandth of a second. Milliseconds measure reaction times (human average: 250 ms), sports timing, video frame rates (33 ms per frame at 30fps), and internet ping times. A blink of an eye takes about 300-400 milliseconds.
