Time for another quick Excel tip.

Lets say the park near your house rents tennis courts by hour. And they charge $10 per hour. At the end of an intense tennis playing week, Linda, the tennis court manager called you up and said you need to pay $78 as rent for that week.

**How many hours did you play?**

*Of course 78/10 = 7.8 hours.*

But we all know that 7.8 hours makes no sense.

We also know that 7.8 hours is really 7 hours 48 minutes.

**So how to convert 7.8 hrs to 7:48 ?**

That is our quick tip for the day.

Simple, assuming the fractional time is in cell A1,

Use below steps to convert it to hours & minutes:

- In the target cell, write =A1/24
- Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
- Select Custom from “Number” tab and enter the code [h]:mm
- Done!

Thats all for now. Stay awesome until next *time*.

Hi Purna..

Again a great tip.. Its a great way to convert Fractional Time..

By the way.. Excel has two great and rarely used formula..

=DOLLARFR(7.8,60)and=DOLLARDE(7.48,60)basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...

This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12

Any ideas why?

@Jason

7.8 in Excel talk means 7.8 days

=7.8*24

=187.2 Hrs

=187 Hrs 12 Mins

If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day

Simple, assuming the fractional time is in cell A1,

Use below steps to convert it to hours & minutes:

1. In the target cell, write =A1/24

2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)

3. Select Custom from “Number” tab and enter the code [h]:mm

4. Done!

Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'

good one

So how do I go the other way and get hours and minutes to fractional time?

If you have 7.5 in cell A1,

- Use int(A1) to get the hours.

- Use mod(A1,1)*60 to get minutes.

If you have 7:30 (formatted as time) in A1

- Use hours(a1) to get hours

- Use minutes(a1) to get minutes.

I had the same issue. You can solve it by changing the format as described above:

Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm

([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)

Thanks guys, these are the tips I'm looking for.

...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time

It doesnt work for greater than 24 hours

It returns 1:30 for 25.5 hours. It should have returned 25:30

Ideally I would right function as

=QUOTIENT(A1,1)&":"&MOD(A1,1)*60

Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.

Thanks very much, extremely useful !
