The form contains this example. Change the values to try your own input.

Convert a duration to days, hours, minutes and seconds. One day is 24 hours and one week is 7 days. Results are rounded to milliseconds.

To convert minutes to decimal hours, divide by 60. The example uses 90 minutes: 90 divided by 60 is 1.5 hours. This is the same duration as 1 hour and 30 minutes, not 1 hour and 5 minutes.

Example input

90 min

Expected result

1.5 h = 1 h 30 min = 5400 s

Try it step by step

  1. Keep the amount at 90 and select minutes as the input unit.
  2. Run the converter and compare the hours and seconds with the expected result.
  3. Change the amount to 150: the result should be 2.5 hours, or 2 hours and 30 minutes.

How to read the result

The fraction of an hour must be multiplied by 60 to get minutes: 0.5 × 60 = 30. In the other direction, multiply hours by 60. Decimal formatting follows the page language, so a decimal comma may appear instead of a decimal point.

Limits and important details

This tool converts fixed durations. A day means 24 hours here; an actual calendar day across a daylight-saving change can be shorter or longer. Use the time-zone tool when you need local clock times.
