To convert years to days: multiply by 365 (or 365.25 for average including leap years). To seconds: multiply by 31,536,000.
1 yr = 365 d = 8,760 h = 525,600 min = 31,536,000 s. A leap year has 366 days (31,622,400 s).
For example, 1 Year (365 days) (yr) = 31536000000 Millisecond (ms).

The common year is a unit of time equal to 365 days, or 31,536,000 seconds.
1 yr = 365 d = 8,760 h = 525,600 min = 31,536,000 s. A leap year has 366 days (31,622,400 s).
To convert years to days: multiply by 365 (or 365.25 for average including leap years). To seconds: multiply by 31,536,000.
Age calculation, financial year reporting, contract durations, academic years, and historical timeline reference.
The year 2000 was a leap year (divisible by 400), but 1900 was not (divisible by 100 but not 400). The Gregorian rule fixes the calendar's drift to 1 day per 3,236 years.
Assuming every 4th year is a leap year — century years must be divisible by 400 (so 1900 wasn't a leap year).
Leap year rule: divisible by 4 = leap, UNLESS divisible by 100, UNLESS also divisible by 400. So 2000 was, 1900 wasn't.
The millisecond is a unit of time equal to 10⁻³ seconds — one thousandth of a second.
1 ms = 0.001 s = 1,000 µs = 10⁶ ns. There are 1,000 milliseconds in one second.
To convert ms to seconds: divide by 1,000. To convert seconds to ms: multiply by 1,000.
Web page load times, video game frame timing (16.67 ms = 60 fps), network ping times, and heartbeat intervals (~800 ms).
Human reaction time to visual stimuli is about 250 ms. A housefly's wing beats once every 4 ms. A humming bird's wing: ~12 ms per beat.
Confusing ms (milliseconds) with Mb/s (megabits per second). In networking, ms measures latency while Mb/s measures throughput.
Your eye blink = ~300 ms. A 60 fps game = 16.67 ms per frame. These are great millisecond benchmarks.
