I am subtracting time i.e. 15:03-14:55 and getting :08 as the answer. I
would like to use :08 as a value of just 8 so that I can use it in a
calculation. For example, I have a pump that pumps water 1080 ml/minm,
if
it pumps between 14:55 and 15:03 I would like Excel to calculate the
number
of minutes, 8, and multiply by 1080 to get the number of mls. However,
Excel
calculates, :08 and multiplies by 1080 gets 0:00.
