To convert minutes in decimal format to a proper Excel time, just divide by 1440. For example, if you have a number that represents minutes in cell A1, use: If A1 contains the number 360 (representing 360 minutes) then the result will be 360/1440 = .25, since 360 minutes = 6 hours = 1/4 day.To see the result formatted in a normal time format, you'll need to change the number format to a time format.or example, if you have a number that represents minutes in cell A1, use: If A1 contains the number 360 (representing 360 minutes) then the result will be 360/1440 = .25, since 360 minutes = 6 hours = 1/4 day.

Convert seconds to hours, minutes and seconds (PHP) Here is a small function that converts number of seconds to an array containing hours, minutes and seconds separately. The first thing we need to do is get the number of hours. To do that we divide $seconds by 3600 (number of seconds in one hour) and use only the whole number of the result. For example, if the supplied time was 4572 seconds then the result of the division would be 1, because 4572 / 3600 is 1.27, which means that there is only one full hour in 4572 seconds. Next step is to find out the number of minutes in the remaining time.
