Minutes to Millennia (min to ky)

1 minute equals 1.90132431×10⁻⁹ millennia (rounded).

1 minute = 1.90132431×10⁻⁹ millennia

How to convert minutes to millennia

To convert minutes to millennia, multiply the number of minutes by 1.90132431×10⁻⁹. The factor is rounded to 10 significant digits. To go the other way, multiply millennia by 525,949,200.

millennia = minutes × 1.90132431×10⁻⁹

Example: 10 minutes = 1.90132431×10⁻⁸ millennia.

Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.

About these units

Minute (min)

Metric (SI)Current unit

60 seconds. Defined as one sixtieth of an hour.

Minute means small, not short. It comes from the Latin pars minuta prima, the first small part, produced when sixty-based division was applied to the hour. Al-Biruni is credited with dividing the hour into minutes, seconds, thirds and fourths around the year 1000, and Roger Bacon used the same scheme in 1267. For everyday life the minute needed hardware: Jost Bürgi is said to have made the first clock with a minute hand, for Tycho Brahe in 1577, and watches got minute hands only after Thomas Tompion's hairspring of 1675 made them accurate enough.

A minute is 60 seconds, exactly 1/60 of an hour, and the BIPM's SI Brochure is the reference for its symbol, min. Civil timekeeping can bend the rule: because of leap seconds, a UTC minute occasionally holds 61 seconds. A negative leap second would produce a 59-second minute, but that has never happened in more than 40 years. People use the minute for cooking, lectures and phone calls, and the same name serves for the arcminute, which is a sixtieth of a degree.

1 minute = 60 seconds (exactly).

Millennium (ky)

CalendarCurrent unit

One thousand years.

Latin supplied the parts of millennium: mille, a thousand, and annus, a year. The plural can be millennia or millenniums. Because a thousand years exceeds any one person's reach, the word acquired religious overtones in the idea of millenarianism, though the unit itself is a plain count of years. When the year 2000 arrived, a new question came with it: was this the start of the third millennium, or was that a year away?

A millennium is 1,000 years, here 1,000 average Gregorian years. The 2001 camp points out that there is no year zero, so the first millennium ran from year 1 to year 1000. The 2000 camp followed the odometer effect, in which the hundreds and thousands digits roll over together. Most people celebrated in 2000, and the celebrations in 2001 were mostly routine, although the U.S. Naval Observatory, Cuba and Japan did mark the strict date. The evolutionary biologist Stephen Jay Gould observed that the strict view dominated at the start of the 20th century and the popular view at its end.

1 millennium = 31,556,952,000 seconds (exactly).
