I was hoping someone could help me with this question. I need to convert a time sting (not sure if that's the right terminology) into a corresponding number. So in cell A1 (time) the input would be 6:00am-8:00am and the corresponding number would be in cell B1 (units) 8. Every 15 minutes is equal to 1 unit. If anyone can give me any answers to this question it would be greatly appreciated.
