Hello everyone,
I just had a question on what the technical name of changing time into decimals is called.

For example 1 hour 15 mins is 1.25, 1 hour 30 mins is 1.50, 1 hour 45 mins is 1.75. So on and so forth. 2 hours 32 mins is 2.53.

The formula in excel from two cells (one with Hours and one with Mins) is
=((A2*60)+B2)/60

However, I do not know the technical name of this time conversion. Is there a name for it?
 

Excel Facts

When they said...
When they said you are going to "Excel at life", they meant you "will be doing Excel your whole life".
What you need to understand about dates and times in excel is…

a date is just a number representing the number of days passed since 1/1/900...and then formatted in a way that we recognize as a date. So, for instance, today (Mon 23 Oct 2017) is actually 43031

Time is actually a decimal part of 1 (day), so 06:00 AM is 0.25, 12 noon is 0.5 and 18:00 (or 6 PM) is 0.75

So, having said that, if TIME is entered correctly, 1 hr 15 minutes (1:15 AM) is actually 0.000868056

When working with time, it is almost always better to work with actual (real) time, rather than using whole numbers to "represent" time
