	Converting hours and minutes into minutes in Excel There is a way to convert time expressed in hours and minutes into minutes only, even though Excel doesn´t have a minutes-only format. Enter a measure of time in hours and minutes, such as 2:25, into any cell, such as A1. In another cell, enter the formula =Hour(A1)*60+minute(A1). Excel will then convert the time into minutes. If the result is still in time format (00:00 or similar), then click the Comma Style button (to the right of the percentage button) on the toolbar or select the General format from Format, Cells, Number.

Set the criteria (as in B6 is greater than 15) and create a format to apply when that condition is met.
