Question

Excel Time Formula

Asked by: mhunts

In column A, I have numeric data of the format 20915, which represents 209 hours, 15 minutes. Note there is no decimal point. I need to convert this to a number of days in column B, such as 8.71875 (general numeric format).

Another example is 21330, which is 213 hours, 30 minutes, which should convert to 8.90 (days).

Okay,

I have a formula that can calculate the correct result. With the original number in A4, I have this formula.

=TRUNC(A4/100)+(A4/100-TRUNC(A4/100))*100/60

The number stored as a result of the formula above is 209.25, which is 209 1/4 hours.

I want this 209.25 to display as 209:15, which means 209 hours, 15 minutes. What is the formatting I should use?

 

by: gtglonerPosted on 2008-02-18 at 17:46:58ID: 20925097

This is about the best I can come up with, it gives you the correct number of minutes, but separated by a dot, not a colon (if I find a solution to that part of it, I'll get back here with it):

=TRUNC(A4/100)+((A4/100-TRUNC(A4/100))*100/60)/100*60

 

by: Miss_SellaneusPosted on 2008-02-18 at 18:03:22ID: 20925152

I added to gtgloner's code. This should do it:
=SUBSTITUTE(TEXT(TRUNC(A4/100)+((A4/100-TRUNC(A4/100))*100/60)/100*60,"#######0.00"),".",":",1)

 

by: Miss_SellaneusPosted on 2008-02-18 at 18:04:58ID: 20925160

Make sure there's enough positions to the left of the decimal in the mask for your purposes.  "#######0.00" would fit any number up to 99999999.99.

 

by: csoussanPosted on 2008-02-18 at 18:11:49ID: 20925181

Try =(LEFT(A1,3)*60+RIGHT(A1,2))/(1440)

See attached spreadsheet for formula.

 

by: csoussanPosted on 2008-02-18 at 18:18:11ID: 20925215

Sorry, I didn't see your question modification.  My above post will convert your number to days - not hours and minutes.  However, if you only want to display 20915 asn 209:15, you can use the following formula.

=CONCATENATE(LEFT(A1,3),":",RIGHT(A1,2))

 

by: byundtPosted on 2008-02-18 at 18:22:02ID: 20925228

mhunts,
You can convert to days using a formula like:
=INT(A1/100)/24+MOD(A1,100)/1440              display as days using a Number format

This value may be displayed like 209:15 using Custom format like
[h]:mm

You may alternatively convert to hours:minutes displayed as text using:
=TEXT(INT(A1/100)/24+MOD(A1,100)/1440,"[h]:mm")

I tried all of your suggestions, but none of them yield the correct result.

Column A: 20915
Column B: 209:15 displayed, but stored as 209.25

I need the number to be displayed as hours:minutes, but stored in decimal minutes. The reason for this is that I need to do mathematical operations on the result in column B. Such as averages.

You can test your solution before postiing by adding a column C, which is column B + 1. The display result should be 210:15 (with a stored result of 210.25).

Thanks for all your suggestions. I think I wasn't clear enough in the question. The result has to be numeric.

 

by: jellPosted on 2008-02-19 at 00:43:01ID: 20926641

I don't think that's possible without the use of two columns. One storing 209.25, and the other using one of the solutions above to show 209:15

Hi - this will do it...

It assumes that there's always two numbers in the minutes counter but it accounts for 0 minutes.

=IF(RIGHT(A1,2)="00",(LEFT(A1,(LEN(A1)-2))/24),(LEFT(A1,(LEN(A1)-2))/24)+(1/(60/(RIGHT(A1,2))*24)))

Cheers.

 

by: Merch_OpsPosted on 2008-02-19 at 01:37:38ID: 20926862

Sorry - forgot to add - you can custom format the above as dd:hh

 

by: roryaPosted on 2008-02-19 at 04:49:35ID: 20927721

As Jell said, you can't do what you want with one cell. Because of the way Excel stores date/time values, 209.25 is 209.25 days and therefore no time format will produce the result you want.
You can use Brad's formula to get the result in days and format it as [h]:mm to get 209:15 but the value in the cell will not be 209.25 so your dependent formulas would have to calculate the decimal value you want from the original cell, not the time formatted one, using a formula like: =INT(A1/100)+MOD(A1,100)/60

Regards,
Rory

 

by: saurabh726Posted on 2008-02-19 at 05:28:26ID: 20928084

Try this...

=text(LEFT(A1,3)&":"&RIGHT(A1,2),"[h]:mm")

This will do the trick for you...

 

by: roryaPosted on 2008-02-19 at 05:35:04ID: 20928127

You don't need the TEXT function if you do that:
=LEFT(A1,3)&":"&RIGHT(A1,2)
does the same thing, but neither solves the problem of displaying 209:15 while putting 209.25 in the cell (since it's impossible!)

 

by: Merch_OpsPosted on 2008-02-19 at 05:48:11ID: 20928203

If you go back to the original question...

Turn 21330 into 8.9 days displayed as 08:21

my formula with a custom format of dd:hh does exactly that:
=IF(RIGHT(A1,2)="00",(LEFT(A1,(LEN(A1)-2))/24),(LEFT(A1,(LEN(A1)-2))/24)+(1/(60/(RIGHT(A1,2))*24)))

 

by: saurabh726Posted on 2008-02-19 at 05:49:13ID: 20928213

Rory on second thoughts it can be done..even if he enters 209.25...it can be changed to 209:15....use this formula....

=text(LEFT(A1,3)&":"&RIGHT(A1,2)/100*60,"[h]:mm")

Out here since you enter in decimals which is at 100 scale..all you need to do is convert that to 60 scale..and i did the text formating to ensure that it works...

merch_ops,
The original question changed completely in the follow-up post, unfortunately!

Saurabh,
The problem is that the OP wants to enter 20915 in a cell and have *one* other cell which contains 209.25 but displays 209:15. The point we are trying to make is that you cannot do that with *one* cell. It's easy with two, as has already been shown.

Hi All:

Would there be some way to apply the concepts of the following to a desired range of cells [i.e. column B]?

I am stuck with 2000 and cannot test since this property is not recognized in 2000.

Bob,
I don't think that would help as it's an application level setting, so it would affect all workbooks, rather than a range of cells. Also you would still be left with the issue of displaying the 25 as 15.
Regards,
Rory

Guess it can't be done in one cell. Will have to create a second.
