I have a spreadsheet which contains the hours individual employees have worked in a month.
This column is set to a custom format [h]:mm:ss. I want to convert the hours worked into an integer.
I'm using this formula to try and convert the values:
=(HOUR(F4)*60+MINUTE(F4)*60+SECOND(F4))/60
Nothing is coming out as expected, though.
For 159:05:45, I get 20.75, for example.
Can anyone explain what's going on and how to correct this?
Hour * 60 gives you minutes
Minutes * 60 gives you seconds
And you're adding both; which immediately doesn't sound right.
If you want the time in minutes, you can do something like that:
=F4*24*60
And format as number.
Date/time is stored in days. Multiply by 24 to get in terms of hours and by 60 to get minutes.
Use =((TEXT(f4,"[hh]")*60)+MINUTE(f4)+(SECOND(f4)/60))

I am completing a time study and recording time in excel. I have numbers like 2.24, etc.. I am trying to add them and average them and I am getting numbers like 9.76 when I really want 10m and 16seconds. Any thoughts to fixing this?
When I change the format to mm:ss it give me wild answers
If 9.76 is a decimal number and it's is in A1, then in B1 you can use:
=((A1-(ROUNDOWN(A1;0)))/0,6+(ROUNDOWN(A1;0)))/24
Also, format of cell with formula must be hours (I've used [hh]:mm:ss)
Applying this, I get:
I've done it in the following way: I used cell formatting, like u:mm:ss (in English locale, this might be h:mm:ss instead).
In one cell, I've put 0:2:24 (zero hours, two minutes, 24 seconds).
In the cell below, I've put 0:7:52.
Adding both cells (inside a cell with the mentioned cell formatting) yielded 0:10:16.
=9.76 value(minutes)
=24*60 number of minutes in a day
=A1/A2 formatted as time
Will show 12:09:46. You can use =MINUTE(A3) to extract the minutes and =SECOND(A3) for the seconds.
Actually if 9.76 means 9 minutes and 76 seconds, you'll need more formulas to extract the minutes and seconds then add them together. You can use =Floor() to get the integer. Subtract to find the .76 and multiply by 100 to get the number of seconds. Then divide by 60 to convert to minutes and add to the 9 whole mins. Now you have the number of mins which you can convert to a time value per the above.
EDIT:
You need to enter in Excel as 0:02:12 then you can add quite nicely. If you don't want to re-enter everything you can do this: =VALUE("0:"&SUBSTITUTE(A1,".",":")) then add. Be sure to convert each individual value BEFORE adding otherwise you might get incorrect results.
I am attempting to sum up hours per day across numerous fields. The issue I am encountering is when the sum passes 24 hour it defaults to 24 hour clock so 01:00:00 for 25 hours when actually I want it to show 25:00:00. Can anyone advise on this please? Many thanks,
Depends how your data is formatted - what happens if you change the custom number format to this:
[h]:mm:ss
The time is stored as a number by Excel and it will only show from 0 to 24 hours. If you format the cell as a number it should be 1.04 which Excel sees as 1.04 days and only uses the .04 when formatted as a time. Add *24 to your calculation and you will get 25.00.
It's a little more tricky to get your desired format hh:mm:as but I'll have a go and get back to you shortly.
In my Excel sheet I have a column with dates and times which looks like this: 27.09.2016 14:02:03
I would like to get the difference between each pair of date in seconds.
For Example: 10.10.2016 13:00:10 - 10.10.2016 13:00:00 = 10s
If I do
= A 1- A2
I get 0,000115741
Can anyone please help me?
The value is in days (24 hours) not in seconds. 10 seconds are (almost) exactly that fraction of 24 hours that you get as the answer. Multiply it with 60x60x24 and you get your 10 seconds.
Alex. S response is good enough, you can also multiply what you are getting by 86400 (which is the result of 60*60*24, you just save some operations) There are other alternatives you can explore. You can take a look to this link:https://www.ablebits.com/office-addins-blog/2015/06/24/calculate-time-excel/
I need to change a value of time from days:hours:minutes, into either hours with a decimal or minutes. My data comes up as 001:05:46 for example. I am having trouble with the leading zeros confusing excel. Any help would be great!
Assuming that your value to parse is formatted in DDD:HH:MM like 001:05:46... There are a lot of ways to do this but here's a simple one. To convert into hours we need to take the days times 24 hours per day, add the hours, and add the minutes times 1 hour per 60 minutes:
=LEFT(A1,3)*24+MID(A1,5,2)+RIGHT(A1,2)/60
To get this value in terms of minutes we multiply by 60 minutes per hour. A possible modification of the original formula to reach this point would be:
=LEFT(A1,3)*24*60+MID(A1,5,2)*60+RIGHT(A1,2)
I am doing some work in Excel and am running into a bit of a problem. The instruments I am working with save the date and the time of the measurements and I can read this data into Excel with the following format:
A B
1 Date: Time:
2 12/11/12 2:36:25
3 12/12/12 1:46:14
What I am looking to do is find the difference in the two date/time stamps in mins so that I can create a decay curve from the data. So In Excel, I am looking to Make this (if the number of mins in this example is wrong I just calculated it by hand quickly):
A B C
1 Date: Time: Time Elapsed (Minutes)
2 12/11/12 2:36:25 -
3 12/12/12 1:46:14 1436.82
I Have looked around for a bit and found several methods for the difference in time but they always assume that the dates are the same. I exaggerated the time between my measurements some but that roll over of days is what is causing me grief. Any suggestions or hints as to how to go about this would be great. Even If I could find the difference between the date and times in hrs or days in a decimal format, I could just multiple by a constant to get my answer. Please note, I do have experience with programming and Excel but please explain in details. I sometimes get lost in steps.
time and date are both stored as numerical, decimal values (floating point actually). Dates are the whole numbers and time is the decimal part (1/24 = 1 hour, 1/24*1/60 is one minute etc...)
Date-time difference is calculated as:
date2-date1
time2-time1
which will give you the answer in days, now multiply by 24 (hours in day) and then by 60 (minutes in hour) and you are there:
time elapsed = ((date2-date1) + (time2-time1)) * 24 * 60
or
C3 = ((A3-A2)+(B3-B2))*24*60
To add a bit more perspective, Excel stores date and times as serial numbers.
Here is a Reference material to read up.
I would suggest you to use the following:
Combine date to it's time and then do the difference. So it will not cause you any issues of next day or anything.
Please refer to the image with calculations. You may leave your total minutes cell as general or number format.
MS EXCEL Article: Calculate the difference between two times
Example as per this article
Neat way to do this is:
=MOD(end-start,1)*24
where start and end are formatted as "09:00" and "17:00"
Midnight shift
If start and end time are on the same day the MOD function does not affect anything. If the end time crosses midnight, and the end is earlier then start (say you start 23PM and finish 1AM, so result is 2 hours), the MOD function flips the sign of the difference.
Note that this formula calculates the difference between two times (actually two dates) as decimal value. If you want to see the result as time, display the result as time (ctrl+shift+2).
https://exceljet.net/formula/time-difference-in-hours-as-decimal-value
get n day between two dates, by using days360 function =days360(dateA,dateB)
find minute with this formula using timeA as reference =(timeB-$timeA+n*"24:00")*1440
voila you get minutes between two time and dates
I think =TEXT(<cellA> - <cellB>; "[h]:mm:ss") is a more concise answer. This way, you can have your column as a datetime.
