Time Conversion Explanation

[KuraiChikara]

Hello,
I had a question about what a particular time conversion is called if it's called anything at all.

Example:
The formula I'm using is
=((A2*60)+B2)/60

If your children did homework for 4 hours and 30 mins. That can be converted to 4.5 or 4.50
If your children watched TV for 1 hour and 26 mins. That can be converted to 1.43
If your children played outside for 3 hours and 4 mins. That can be converted to 3.07

Hours	Mins	Converted
3	4	3.07

My question is, is there a name for the time conversion? Or is it simply time represented in decimal form?

In your examples you are converting time in hours and minutes to hours - 4 minutes being 0.066666 ... hours.

As far as I know, it is simply known as expressing the time in hours or, if you someone who is "picky", decimal hours.

Thank you for that, that helps out. I've been doing that time conversion for years and recently ran into someone who needed it explained. I advised them "time represented in decimal form." But that wasn't good enough.

As far as I am concerned, it should have been.

Well ... Excel date/time is already in decimal time -- decimal days. I think the clarification is appropriate.

I'm following up on my own thread because I found the answer I was looking for.

My fellow posters in this thread explained that my examples: IE 1 minute is represented as 0.02, is simply representing ALL time as an hour or "decimal hours." However, there is a name for it. It's called "The 100 Minute Clock." And if you Google it in images, you will find charts that represent what I was explaining. I've been using it for years, I just didnt know that there's an actual name for it and someone else might need this information too. Now I have a name and an explanation of it's function IE" The 100 Minute Clock can represent all time as a fraction/decimal hour."

I agree. Only some archaic history buff would note the possible confusion.
