How to get time difference as minutes in Excel?

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.

I think this will work:

• A1 6:23
• B1 8:23
• C1 =(B1-A1)*24*60

Just make sure you format C1 as "General"
