Unit converter

Minutes to hours.

Convert min to h and h to min. Type in either box and the other follows. Timesheets, cooking and parking all want this, and 90 minutes is 1.5 hours rather than 1.30.

Definitions

  • The minute is exactly 60 seconds — one of the few units SI accepts without being decimal, inherited from Babylonian counting.
  • The hour is exactly 3600 seconds.
  • This conversion is exact by definition. 1 min = 0.01666666667 h.
  • 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 hours in a minute (0.0166667), how many minutes in an hour (60), and what 90 min is in hours (1.5 h).
