To convert months to days: multiply by 30.44 (average). To convert to weeks: multiply by 4.35 (approximate).
1 average month ≈ 30.44 days ≈ 4.35 weeks ≈ 730.5 hours ≈ 2,629,800 seconds.
For example, 1 Month (Average) (mo) = 2629800000 Millisecond (ms).

The average month is a unit of time equal to approximately 30.44 days (2,629,800 seconds), representing 1/12 of a Gregorian calendar year.
1 average month ≈ 30.44 days ≈ 4.35 weeks ≈ 730.5 hours ≈ 2,629,800 seconds.
To convert months to days: multiply by 30.44 (average). To convert to weeks: multiply by 4.35 (approximate).
Billing cycles, rent payments, project milestones, medication tracking, and age calculations (especially for infants).
The mnemonic '30 days hath September' dates to the 13th century. February's 28 days result from Augustus taking a day for August from February.
Treating all months as 30 days. For precise calculations, always account for actual month lengths.
The knuckle trick: make fists, count across knuckles (bumps = 31 days, valleys = 30 or fewer). Start with January on the first knuckle.
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.
