Time Conversion: Convert A Time From Hours/Minutes To Hours/Tenths

Oct 10, 2009

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 a column of tasks that take a certain amount of time to complete formated as h:mm:ss. I want to total the column and convert the total to days, hours and minutes. Is that posible and if so how do I configure a formula and format the cell? example:

Just basic enter a start time in column A a finish time in column B and column C gives you total in hours and minutes and then maybe a way to sum those hours and minutes. how to do "Math" on time and how it should be entered (formatted) for it to work properly.

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 need a vba code , i have time in column F like 8:30 , 3:30 , 5:30 , 8:30 , 9:30.......i need a macro which will add 00:30 in all cells in column F if time is less than 7.00 hrs

basically I am trying to make a time calculator for work, I want it to automatically add the hours up but then also minus break times and then give me a whole paid total hours worked that week.

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 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"

if someone called me at 4:55pm and ended the call at 5:10pm, the whole call lasted 15 minutes. So, I want to show on excel that the call lasted 5 minutes in the 16th hour of the day (4:55pm) and 10 minutes in the 17th hour of the day (5:10pm), for a total of 15 minutes.

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!

I have a spread sheet with a colum showing average time to complete a task. This is currently shown as Days:Hours:Minutes:Seconds (4:19:33:19). I meed it to be shown purely as minutes, or at least as hours and minutes.

I have a formula which will calculate the number of hours and minutes between two military times. I would like it to calculate the total number of minutes instead of hours and minutes. I have uploaded a small example of what i have so far.

find a formula that will calculate the hours between the two below values but only take in to consideration the business hours (from 9 to 17) and exclude any weekends?

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

I have a database which shows a time some one came into work and a time they left. Formatted as HH:MM. I can minus the time they left from the time they came in...to work out how many hours they worked. However, whenever i want to work out how many mintes it is (time left - time in * 60). It does not seem to work.

I am trying to use the Mod function to convert the following:

I have time in hours in A1 as 12.66 and I need it to convert to 12 hours in A2, 39 minutes in A3, and 36 seconds in A4. What formula can I use to achieve this?
