Converting Clock Time to a DecimalDate: 06/04/99 at 21:20:59 From: Mike Lopez Subject: Converting clock time to decimals I need the formula for converting a time range to a decimal. For example: 2:00-2:45 = .75 Please help! Date: 06/04/99 at 22:16:31 From: Doctor Jaffee Subject: Re: Converting clock time to decimals Hi Mike, The key to solving your problem is realizing that you have to use the fact that there are 60 minutes in an hour. For example, 30 minutes is half an hour because 30/60 = 1/2. Furthermore, 1 divided by 2 is 0.5, the decimal value. 50 minutes is 50/60 of an hour and 50 divided by 60 is .833333... So, in general, take however many minutes you have and divide by 60 and you will have the decimal value of that amount of time. I hope this is helpful. - Doctor Jaffee, The Math Forum http://mathforum.org/dr.math/ |
