1. Convert time between hour, minute, second, or day with conversion factor. As we known, 1 hour = 60 minutes = 3600 seconds =1/24 day. So we can convert the time measurement with multiplying these factors. Convert between hours to seconds:
Divide the number of minutes by 60 again to convert seconds to hours. There are also 60 minutes in an hour, so we use the same process, dividing by 60, to determine how many seconds are in an hour. 1  Example: How man hours is 7200 seconds?  7200 / 60 = 120 minutes.
