To convert millennia to years: multiply by 1,000. To centuries: multiply by 10.
1 millennium = 1,000 years = 100 decades = 10 centuries ≈ 365,250 average days.
For example, 1 Millennium (mil) = 525600000 Minute (min).

A millennium is a unit of time equal to 1,000 years, or approximately 365,250 days (31,536,000,000 seconds based on 365-day years).
1 millennium = 1,000 years = 100 decades = 10 centuries ≈ 365,250 average days.
To convert millennia to years: multiply by 1,000. To centuries: multiply by 10.
Archaeological dating, geological time references, long-term environmental projections, and civilization-scale history.
The 'Y2K bug' at the turn of the millennium cost an estimated $300 billion to fix worldwide. Writing was invented about 5 millennia ago.
Like centuries, the 3rd millennium began Jan 1, 2001, not 2000 — though the popular celebration was in 2000.
Think of milestones: ~10 ka = agriculture, ~5 ka = writing, ~2.5 ka = classical civilizations, ~0.5 ka = printing press.
The minute is a unit of time equal to 60 seconds, or 1/60 of an hour.
1 min = 60 s = 1/60 h = 60,000 ms. There are 1,440 minutes in a day and 525,960 in a year.
To convert minutes to seconds: multiply by 60. To convert minutes to hours: divide by 60.
Meeting schedules, cooking times, exercise intervals, transit timetables, and phone call durations.
The minute hand on a clock rotates 360° per hour (6° per minute). There are exactly 525,600 minutes in a non-leap year.
Using decimal hours incorrectly: 1.5 hours = 90 minutes, not 1 hour 50 minutes. The base-60 system catches people off guard.
The Babylonians gave us base-60 time. That's why we have 60 seconds per minute and 60 minutes per hour — it's not decimal!
