# Decimal Time - Auto Sum Hours And Minutes Columns

Nov 21, 2012
I am a truck driver and keep a record of my loading times when I am loading and unloading. At the end of a trip i transfer all the data to my computer, then "auto sum" the "HOURS" and the "MINUTES" columns. At the bottom of ech trip I end up with figures, lets say 32 (hours) in column "J" and 303 (minutes) in column "K".

Now 303 minutes is {5 hours and 3 minutes}. Now we all know that mathematically we can work out that {3} minutes is 0.05 of 1 hour and that would make the total time worked 32 (hours) + 5 (hours(from the minutes)) + the last 3 minutes and the total is 37 hours and 3 minutes.

What I am in need of is a formula that will take the hours in column "J" add the hours from column "K", leaving the minutes to be converted to 0.05, giving me a total in cell "M29" that can then be multiplied by the wage rate in cell "M30", giving me an amount that I should be paid in cell "M31"

I have a spreadsheet that keeps track of my flight time by the day and then totals it for the month however, I keep it in a decimal number (i.e. 89.23). I want the final total number to be in Hours and Minutes hhh:mm and can not for the life of me figure out the formula to make it come out in hours and minutes. I can either convert the one final decimal number over to hours and minutes or add the entire collumn of decimal numbers and have THAT total converted to hours and minutes. It's doesn't matter to me. I just can't figure out the formula.

When I am converting a time from Hours/Minutes to Hours/Tenths, Excel is not converting it consitantely. EXAMPLE: 1:15 = 1.25. When I format the cell to present only one place past the decimal point, sometimes the cell will round up to 1.3, and other times it will round down to 1.2. What am I missing?

I have two columns A and B. Column A contains problem title and column B is duration minutes. In column B we enter always min and seconds it took us to resolve certain issues (22.15 = 22 minutes and 15 seconds) . At the end of the month I need to run a report for my manager to show her by problem title how long it took my group to resolve issues and it should output as Hours/min/days.

I've got a worksheet that deals with dates and time. Similar to a checkbook, I need to take the balance and subtract what's taken from that. But the writer copied this from another software program and it's in this format. How do I convert it to a time format? Or is that what I really need? Right now the taken and balance are both in a general format.

I just need to know on any of the given days what the balance of this person's time was in hours and minutes.

I have used the format [hh]:mm in a cell for 24 hr clock calculations. Why do I have to enter the numbers with a colon when I populate the cells? Is there a way to set it up so I just type in the four numbers and the colon between the hours and minutes populates itself?

I want a forumal to do in excel.

Assuming that a workday is from 8:30am to 5:00pm. (also need to not calcualte Saturday and Sunday but this example doesn't show it).

Wednesday, 7/18/07 at 4:00pm (minus) Friday, 7/20/07 at 9:00am (should equal) 10 hours or 1 day, 1 hour and 30 minutes.

Basically what I want to do it determine how much work time has elapsed from the time a message was left on voicemail to the time that someone picks that message up. We only want to assume that a message can be retrieved duruing business hours but a message can be left at anytime!

formulae that converts % into time and visa-versa.

I.e 1.5 hrs = 1.30 hours ( i.e 90mins)

or the other way round

1.30 hours = 1.5 hrs..

The below seems to work but I'm wondering if there might be a better way. I'm trying to keep an ongoing up-to- date and accurate time. my code is as follows:

Private Sub Workbook_Open() ' placed inside thisworkbook

Call TimeUp

End Sub

Sub UpdateTime() ' placed in module

If Range("A4") = TimeValue("00:00:00") Then

Application.OnTime Now + TimeValue("00:01:00"), "TimeUp"

Else

UpdateTime2

End If

End Sub

Sub TimeUp()

[a1] = Time

UpdateTime

End Sub

Sub UpdateTime2()

[a1] = Time

Application.OnTime Now + Range("A4").Value, "TimeUp"

End Sub

Does anyone know if there is any way to improve the Code or formulas within the Cells?

I'm trying to convert 3786 minutes to day:hours:minutes. So divided it by 1440 which is 2.63... but I want this displayed in the worksheet as 2 days 1 hour and 3 minutes (02:01:03), I just can't seem to get it to work and it seems quite simple... but I'm missing something.... I was trying a custom format like dd:hh:mm or [d]:hh:mm and I was also trying a convert function and =day/1440+hour +minute

1) The output of an excel duration is : 22.00:8.00:25.00 ( day:hour:minutes ) - excel cannot average and work with this number format

2) resolution - =(LEFT(L2,4))+MID(L2, FIND(":",L2)+1,4)/24+MID(L2, FIND(":",L2,7)+1,4)/1440 as an array and Custom Format the cell as [h]:mm - works perfectly.

Q: to be conistent, the initial reporting is dd:hh:mm and then I convert to hh:mm so that excel can process the data. How can I convert from hh:mm to dd:hh:mm so that the excel report can be consistent in presenting the data to senior management?

example attached.
