Help with time formatting

[Tom]

I have a cell that totals in hours and minutes
I need to convert that cell automatically to total in minutes
in other words I need 2:40 minutes to show as 160 minutes.
I tried formatting the cell as :mm using custom formating and it didn't work
any suggestions as to how to convert this would be very much appreciated

Try something like:

=IF(HOUR(A1)>0,HOUR(A1)*60,0)+ROUNDUP(MINUTE(A1),0)+1

HTH

Try a custom number format of:
[mm]

2:40 does mean 2 hours 40 minutes, right?

=A1*24*60 and format as number or general, not as time.
