How to get time difference as minutes in Excel?

I have time values in two cells in an Excel sheet and I need the difference of the times in minutes.

The cells in the Excel are like below:

   A        B        C
1  6:38     8:23     1:45:00

A is the start time
B is the end time
C is the time difference (B1-A1) which is displayed in hh:mm:ss format

A and B cols are formatted as custom hh:mm and cell C is formatted as custom hh:mm:ss.

But I need to get in the value in cell C1 as 105 instead of 1:45:00.

Could you please help in displaying time only in minutes and giving the right format?

Just set the cell to be shown in numerical format and it will show a decimal number.

The integer part corresponds to the date value (i.e. the day) and the decimal part to the time of the day.

If you multiply the numerical value of 1:45 (which is 0,07) by 24x60 (the number of hours in a day and the number of minutes in an hour) you will obtain the value in minutes of your cell (105).

Just format your cell as [mm].

The square brackets around the mm tell Excel to show the total rather than what would be shown if you took the total hours off. The brackets also force Excel to interpret mm as minutes, not as the month. (Without the brackets, m and mm refer to the month if not preceded by h or hh for hours or followed by ss for seconds.)

So, where 1:45:00 with format mm:ss would ignore the hours and show 45:00, both [m]:ss and [mm]:ss will show as 105:00, and both [m] and [mm] would show 105 (where m and mm would show 12, being the month of Excel's default date, which is December 31, 1899).

This also works for hours and seconds. Like 27:10:59 with h:mm would show 3:10, but both [h]:mm and [hh]:mm show 27:10, while both [h] and [hh] show 27. And s would show 59, but [s] gives 97859.
