Unit converter
Hours to minutes.
Convert h to min and min to h. Type in either box and the other follows. Sixty to the hour, so 2.5 hours is 150 minutes rather than 2 hours 50.
| h | min |
|---|---|
| 0.25 h | 15 min |
| 0.5 h | 30 min |
| 0.75 h | 45 min |
| 1 h | 60 min |
| 1.5 h | 90 min |
| 2 h | 120 min |
| 3 h | 180 min |
| 4 h | 240 min |
| 8 h | 480 min |
| 24 h | 1440 min |
- Conversion goes through s in both directions, so neither figure is rounded on the way.
Definitions
- The hour is exactly 3600 seconds.
- The minute is exactly 60 seconds — one of the few units SI accepts without being decimal, inherited from Babylonian counting.
- This conversion is exact by definition. 1 h = 60 min.
- Months and years are not fixed durations. The year here is the exact Julian year (365.25 days); the month is a mean Gregorian month, and a calendar month still varies from 28 to 31 days.
How it works
One direction multiplies and the other divides by the same number, so nothing is lost by going back and forth.
The value passes through s, the unit every other time unit on the site is defined against, rather than a number written into this page on its own. That is why the figure here, the figure in the table above and the general time converter always agree.
Display precision limits significant figures rather than decimal places, because one fixed number of decimals is useless across a range this wide. Very large and very small results switch to scientific notation with a proper superscript exponent. The editable box always holds a plain number at full working precision, so you can carry on from either side.
Common questions this answers: how many minutes in an hour (60), how many hours in a minute (0.0166667), and what 2 h is in minutes (120 min).
