Converting times into days, hours, minutes, or seconds has many practical applications. If you are working on a problem with several time variables, you must convert all the times to the same unit of measure in order to obtain the correct answer. Below are the conversion formulas for days, hours, minutes, and seconds.

You can also plug values into the convenient conversion calculator on the left. It will give you the duration of time in terms of days, hours, minutes, and seconds. It will also display the time in the standard form DD:HH:MM:SS, where DD is the number of days, HH is the number of hours (less than 24), MM is the number of minutes (less than 60), and SS is the number of seconds (less than 60).

1 day = 24 hours
         = 1440 minutes
         = 86400 seconds

1 hour = 1/24 days
          = 60 minutes
          = 3600 seconds

1 minute = 1/1440 days
             = 1/60 hours
             = 60 seconds

1 second = 1/86400 days
             = 1/3600 hours
             = 1/60 minutes
