Unit converter

Time.

Convert min to h, or pick any of the 16 units in the menus. Type in either box and the other follows. Seconds through to years, with the caveat that months and years are not fixed durations — the year here is the Julian one used in astronomy.

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.
  • 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.
  • The menus include h + min and min + s, which keep the whole hours whole and put the remainder in minutes — so a value reads 2 h 30 min rather than a decimal.
  • 14 of the 16 units are exact by definition; the rest are conventional or measured values. The display says which kind you are looking at.

How it works

Every value is converted into seconds and then back out into the unit you asked for. One route covers every pairing in the menus, so an unusual combination is no less accurate than a common one, and adding a unit affects only that unit.

Both boxes are live. Whichever one you last typed in is the source, changing either menu recalculates straight away, and Swap exchanges the units and the values so the number you are reading stays where you are looking.

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 60 min is in hours (1 h).
