I'm using an excel document to track my hours at work (this is my 3rd question about it)
I'm trying to figure out how to multiply a time (i.e. 62:05, which is how long I have worked for over 2 weeks), by my hourly rate (11$/hr) and get approximate gross earnings in this format: $667.43
my time format is [hh]:mm and the 11/hr format doesn't do anything other than the total being 29.0000382 something.
Consider this formula:
=A1*24*B1
I have about 160k rows of data which consists of temperatures and flow rates. I need to get it down to being a bit more manageable. I would like to have an average temperature and flow rate each hour instead of several values each minute. I'm not much of a programmer but I don't think this would be a problem if it were the case that I had the same amount of measurements each hour, which is not the case. Each hour has between 200-400 data points and I'm not sure how I would go about this problem. The output I want is something like
date - hr - average1 - average 2 ... and so on.
How the sheet looks
Does anyone have a suggestion of how to go about this?
Sincerely,
This is how it looks in a pivot table. I've put in some dummy data which has two different days and two different times to test it.
To get the date without the time I've used
=floor(B2,1)
because date-times are stored as decimal numbers where the whole number part contains the date and the fraction part contains the time.
To get the hour I've just used
=hour(B2)
My test data looks like this
and the resulting pivot table looks like this
I had to use Value Field Settings and Number Format to tidy up the formatting of the date and average columns.
I'm doing some benchmarking, and I want to use Excel to produce graphs of the results. I've got a simple but annoying problem which is baking my noodle.
The problem is that Excel insists that "time" means a time of day. It refuses to let me work with time durations. When I try to say "three minutes and six seconds", it misinterprets this as "three minutes and six seconds past midnight", which isn't what I meant at all.
I can work around the problem by laboriously converting everything to seconds. But then all my graphs are labelled in seconds, not minutes and seconds. Plus it's a pain to have to keep typing in =3*60+6 rather than just 3:06. And once I've done it, I have to look at the formula to check whether I entered the data correctly [and didn't screw up the formula].
Does anybody know how I can make Excel work with a time duration not anchored to a specific time of day?
You can easily do this with the normal "Time" data type - just change the format!
Excels time/date format is simply 1.0 equals 1 full day (starting on 1/1/1900). So 36 hours would be 1.5. If you change the format to [h]:mm, you'll see 36:00.
Therefore, if you want to work with durations, you can simply use subtraction, e.g.
A1: Start: 36:00 (=1.5)
A2: End: 60:00 (=2.5)
A3: Duration: =A2-A1 24:00 (=1.0)
Use format d "days" h:mm:ss or [h]:mm:ss, depending on your needs.
Say you have a duration of 30h 12m 54s:
h:mm:ss -> 6:12:54 (not correct for a duration)
[h]:mm:ss -> 30:12:54
d "days" h:mm:ss -> 1 days 6:12:54
Variations are possible: I like something like d"d" h"h" mm"m" ss"s" which formats as 1d 6h 12m 54s.
The custom format hh:mm only shows the number of hours correctly up to 23:59, after that, you get the remainder, less full days. For example, 48 hours would be displayed as 00:00, even though the underlaying value is correct.
To correctly display duration in hours and seconds (below or beyond a full day), you should use the custom format [h]:mm;# In this case, 48 hours would be displayed as 48:00.
Cheers.
With custom format of a cell you can insert a type like this: d "days", h:mm:ss, which will give you a result like 16 days, 13:56:15 in an excel-cell.
If you would like to show the duration in hours you use the following type [h]:mm:ss, which will lead to something like 397:56:15. Control check: 16 =(397 hours -13 hours)/24
I don't know how to make the chart label the axis in the format "X1 min : X2 sec", but here's another way to get durations, in the format of minutes with decimals representing seconds (.5 = 30 sec, .25 = 15 sec, etc.)
Suppose in column A you have your time data, for example in cell A1 you have 12:03:06, which your 3min 6sec data misinterpreted as 3:06 past midnight, and column B is free.
In cell B1 enter this formula: =MINUTE(A1) + SECOND(A1)/60 and hit enter/return. Grab the lower right corner of cell B2 and drag as far down as the A column goes to apply the formula to all data in col A.
Last step, be sure to highlight all of column B and set it to Number format (the application of the formula may have automatically set format to Time).
Highlight the cell(s)/column which you want as Duration, right click on the mouse to "Format Cells". Go to "Custom" and look for "h:mm" if you want to input duration in hour and minutes format. If you want to include seconds as well, click on "h:mm:ss". You can even add up the total duration after that.
Hope this helps.
The best way I found to resolve this issue was by using a combination of the above. All my cells were entered as a Custom Format to only show "HH:MM" - if I entered in "4:06" (being 4 minutes and 6 seconds) the field would show the numbers I entered correctly - but the data itself would represent HH:MM in the background.
Fortunately time is based on factors of 60 (60 seconds = 60 minutes). So 7H:15M / 60 = 7M:15S - I hope you can see where this is going. Accordingly, if I take my 4:06 and divide by 60 when working with the data (eg. to total up my total time or average time across 100 cells I would use the normal SUM or AVERAGE formulas and then divide by 60 in the formula.
Example =(SUM(A1:A5))/60. If my data was across the 5 time tracking fields was the 4:06, 3:15, 9:12, 2:54, 7:38 (representing MM:SS for us, but the data in the background is actually HH:MM) then when I work out the sum of those 5 fields are, what I want should be 27M:05S but what shows instead is 1D:03H:05M:00S. As mentioned above, 1D:3H:5M divided by 60 = 27M:5S ... which is the sum I am looking for.
Further examples of this are:
=(SUM(G:G))/60 and
=(AVERAGE(B2:B90)/60) and =MIN(C:C) (this is a direct check so no /60 needed here!).
Note that your "formula" or "calculation" fields (average, total time, etc) MUST have the custom format of MM:SS once you have divided by 60 as Excel's default thinking is in HH:MM (hence this issue). Your data fields where you are entering in your times should need to be changed from "General" or "Number" format to the custom format of HH:MM.
This process is still a little bit cumbersome to use - but it does mean that your data entry is still entered in very easy and is "correctly" displayed on screen as 4:06 (which most people would view as minutes:seconds when under a "Minutes" header). Generally there will only be a couple of fields needing to be used for formulas such as "best time", "average time", "total time" etc when tracking times and they will not usually be changed once the formula is entered so this will be a "one off" process - I use this for my call tracking sheet at work to track "average call", "total call time for day".
Let's say that you want to display the time elapsed between 5pm on Monday and 2:30pm the next day, Tuesday.
In cell A1 (for example), type in the date. In A2, the time. (If you type in 5 pm, including the space, it will display as 5:00 PM. If you want the day of the week to display as well, then in C3 (for example) enter the formula, =A1, then highlight the cell, go into the formatting dropdown menu, select Custom, and type in dddd.
Repeat all this in the row below.
Finally, say you want to display that duration in cell D2. Enter the formula, =(a2+b2)-(a1+b1). If you want this displayed as "22h 30m", select the cell, and in the formatting menu under Custom, type in h"h" m"m".
What I wound up doing was: Put time duration in by hand, e.g. 1 min, 03 sec. Simple but effective. It seems Excel overwrote everything else, even when I used the 'custom format' given in some answers.
I'm creating a report which display duration of time (in hours) between two points in time.
e.g.
Duration between 10:00 to 13:30 equals 3 hrs 30 minutes
This information is being saved into a spreadsheet (excel) in one "duration" column, titled "Duration (hrs)". The column needs to be sortable to allow sorting by longest duration, etc.
Should this be displayed as 3.5 or 3.30 using a numerical column format? Or as 03:30 using a time format? Is there a standard for this or purely down to preference?
Appreciate your thoughts!
Thanks,
Andy
Note also that if you use "hh:mm" for your time format, that will just give you max 24, so even if it goes over several days, you won't see more than 24 hours. If you want the TOTAL number of hours, use "[hh]:mm" to see e.g. 45:32
I think it's probably just down to preference - either method should work and be sortable
For a time format you can just subtract, e.g.
=B2-A2
or for decimal just multiply by 24
=(B2-A2)*24
Personally I think that time durations should be kept in time format.....
I I'm have small headache caused today by excel and the way it takes control of everything. I have two time values I need to add together then divide by a value I got charged for that time to work out how much it cost me an hour.
so say I was charged day on for 12:30:00
on day 2 I was charged for 13:20:00
and day 3 I was charged for 20:30:00
In total it cost me £1000
The calculation would be
£1000 / (12:30:00 + 13:20:00 + 20:30:00 = 46:20:00)
I would guess to get the answer I would
1000 / Sum(12:30:00+13:20:00+20:30:00) = price per hour
But it doesn't...
I guess I need some sort of convert function on the time or to divide it by 24 to get hours but I'm stuck
Help would be hugely appreciated!
Excel represents times as fractional days, so your function is actually representing the rate per day.
Assuming your times are in cells A1:A3, you can adjust your function to something like:
1000 / Sum(A1:A3) / 24
which will give you the rate per hour (by my calculations, £21.58/hr).
As others have mentioned, you will need to set the cell to a currency format.
Excel should be performing the calculation correctly, but it is just showing as a time. Format the result cell as "number" instead.
You can use the HOUR and MINUTE functions to get the hour and minute portions of the time values, however as lc mentions, you do need to ensure that the formatting of the cell is set to Number, as it will default to a time.
Assuming you have your hh:mm:ss values running down the page (column A), in the next column put the formula
=(A1-INT(A1))*24
underneath this you can put your formula
= 1000 / SUM(A1:A3)
but don't forget to format it as Number.
