I'm making calculations on production cost (in number of resources) and duration.
I have a process that takes 5 minutes. Using the Duration format, I would enter that as 00:05:00.
I want to queue up this process a certain number of times and calculate the total duration. The output should either be something like 16:35:00 or 5 02:15:00. A "d HH.mm.ss" format.
How, in Google Sheets, do I multiply a Duration by an integer to get a total Duration? To be clear, I am not doing a summation of a column of durations. I am taking a duration constant, such as 5 minutes or 25 minutes, and multiplying it by an integer representing the number of times the process will be run, consecutively.
All these attempts resulted in Formula Parse Error:
=(5*00:05:00)
=(112*00:05:00.000)
=(VALUE(C27)*00:05:00)
=MULTIPLY(VALUE(C27),00:05:00.000)
Well, blow me down. I came up with a workaround while I was trying different ways to fail. I assigned 00:05:00 to it's own cell with the Duration format, then referenced that cell in the formula.
I.E. =C27*J7 gives me 9:20:00 when C27 equates to 112 (it's a summation of it's own) and J7 is the cell holding 00:05:00.
Still doesn't give me days when it goes over 24 hours, and I'd rather have the duration value as a constant in the formula, but it's a step forward.
Would something like this work for you?? It's no longer a number, but if it's for expressing the amount in your desired format it may be useful:
=IF(ROUNDDOWN(W2*W3),ROUNDDOWN(W2*W3)&"d "&TEXT(W2*W3-ROUNDDOWN(W2*W3),"hh:mm:ss"),TEXT(W2*W3,"hh:mm:ss"))
Change the cell references, obviously
PS: If you want to have the value as a constant in your formula, you can try to change the cell reference with TIME function within your formula:
In both Excel and Google spreadsheet, DATE are represented in a number start counting from 1899/12/30,
which...
1 is equal to 1 day
1/24 is equal to 1 hour
1/24/60 is equal to 1 minute
1/24/60/60 is equal to 1 second
you can do like:
=TODAY()+1 which gives you tomorrow, or...
=TODAY()+12/24 which gives you "date of today" 12:00:00
and when you are done with the calculations, you can simply use a TEXT() to format the NUMBER back into DATE format, such as:
=TEXT(TODAY()+7 +13/24 +15/24/60,"yyyy-mm-dd hh:mm:ss")
will return the date of a week away from today at 01:15:00 p.m.
This date/time format doesn't requires a full date to work, you can get difference of two time format like this:
=TEXT(1/24/60 - 1/24/60/60,"hh:mm:ss")
since 1/24/60 is 1 min, and 1/24/60/60 is 1 second,
this formula returns 00:00:59, telling you that there is a 59 seconds diff. between 1 min and 1 sec.

I hope everyone reading this is doing well. I am making attendance sheets on Google Sheets that also calculates the salary of the person. It is entirely automated except for one part, the part that calculates salaries.
For that I need to separate the Hours and Minutes worked so that I can calculate the salary accurately based on 60 minutes instead of the first half being in hours and the second from a percentage of 100.
It coverts the hours into days and omits the remaining hours. Please assist. Thank you!
What it does
What it should do
HOUR() returns the hour component of a specific time, so it will always return a value between 0 and 23.
In Google Sheets, times are just numbers where 1 indicates 1 day. So a duration of hh:mm:ss means hh/24 + mm/24/60 + ss/24/60/60 which means hours_in_a_day + minutes_in_a_day + seconds_in_a_day. (You can see this if you format the cell as "Number")
So, if you want to extract the hours from a duration, you have to multiply it by 24 and take the INT().
=INT(B20*24)
Spreadsheet time values such was elapsed hours are in units of days. In your spreadsheet, salary is recorded per hour. To multiply the hours by the salary, first convert the salary per hour to salary per day, and then multiply by the elapsed hours, like this:
=n((B23 * 24) * B20)
The n() wrapper is there just to get the number format right. You can also leave it out and format the formula cell as Format > Number > Currency.
See this answer for an explanation of how date and time values work in spreadsheets.
I am recording my time spent on a project in google excel sheet. There is a column which does addition of the recorded time and output total time to column say D40. The output time looks like <hoursspent>:<minutesspent>:<secondsspend>. For example 30:30:50 would mean that i have worked for 30 hours and 30 minutes and 50 seconds on a project.
Now, I was using this formula to calculate my total invoice
=(C41*HOUR(D40))+(C41*((Minute(D40)/60)))+(C41*((SECOND(D40)/3600)))
Where C41 cell contains my hourly rate (say $50).
This is working fine as long as the numbers of hours that i have worked are less than 24. The moment my numer of hours go above 24. The Hour function return the modulus value i.e., HOUR(30) would return 6.
How can I make this calculation generic in a way that it oculd calculate on more than 24 hours value too.
Try
=C41*D40*24
and change formet on the result as $
one hour is part of a day, as you know 1/24th of a day, that's why you could multiply by 24 to get hours, and then multiply it by the rate
Try below formula-
=SUMPRODUCT(SPLIT(D40,":"),{C41,C41/60,C41/3600})
When you store a value as HH:mm:ss into an Excel sheet, it automatically formats it as a Time, so it makes sense that HOUR modulos by 24.
Which is why you can simply ignore it. If you have a cell that is formatted as currency (FORMAT > Math > Currency) or any other normal Number-like format, then you can see, if you perform a numerical operation like multiplication, that it stores times like "30:30:50" as if it were a TIMEVALUE with a value over 1. Simply multiply that by 24, and then by your hourly rate, and you'll get your value, i.e,
=D40 * C41 * 24 :
Just replace HOUR(D40) with INT(D40)*24+HOUR(D40)

I want sum of all duration entries in x hours x minutes x seconds like i have more then 1000 rows of duration when i try to use =SUM(C2:C100) I am not getting sum of total duration after sum of 24:00:00 24 hours it starts from 00:00:00
for example sum of total duration gets 24:00:00 between range of c1:c8 it will start from 00:00:00 from c9: next range kindly assist me how to overcome this issue
try:
=ARRAYFORMULA(TEXT(SUM(IFERROR(TIMEVALUE(C:C))), "[h]:mm:ss"))

Wherever you put the =SUM(), Select that cell and do Format>Number>More Formats>Custom Number formatting, and put the same formatting that Player0 put in his answer:
What worked for me to resolve a similar problem was a suggestion by user ttarchala in Google Sheets Query multi condition sum of time duration.
I used N() function as he said, and my final formula for the duration is:
=IF(To<>"", N(To-From+(To<From))*24, "")
with To and From being Named ranges for End Time and Start Time respectively.
N() function converts the time delta into a number. Multiplied by 24, this gives the hours in decimal format, such as 2 hours 30 minutes = 2.5 hours.
From there on, there is no problem with using the built-in Sum function to calculate the total duration as a decimal. Such as, the total duration of 27 hrs 10 minutes is shown as 27.16. This sufficed for my purposes.
Time delta is calculated using a formula from https://webapps.stackexchange.com/questions/104829/calculate-time-difference-between-times-past-midnight to take into account past-midnight differences.
And the first condition, To<>"", makes sure the formula is not showing in empty cells. As soon as the End Time is filled into "To" column, the decimal duration is calculated. Then it can be used in the regular Sum function.
This seemed shorter and easier than the formulas suggested above so I am sharing it in the hopes it may help someone else. Using thus formula, I just added up the Sum of time I spent looking for this solution: 3.34 hours :)
It's a formatting problem. You formatted your reply as HH:MM:SS, therefore the number displayed is not showing the date, which would have been incremented by one. If you multiply your sum by 24, and then format the result as a pure number, you will get a number that goes above 24, and will show you the number of hours, and its decimals. If you use those hours in further calculations, the result will be correct.
In cell C1, use the formula
=IF((B1-A1)>=0, B1-A1, 1+B1-A1)
Explanation: the problem is durations that exceed the 24 hour limit, as you say.
Google Sheets has become a bit deceptive here, as it will show the correct duration for the individual time interval, but if you SUM over it, it will actually deduct the value!
A B C
23:39 1:10 1:31
When you SUM then Google Sheets will see the value in cell C1 as if it was the beginning of the same day as the time in A1. So when you in C1 do =B1-A1 then it will register as a negative duration! But it won't show up as that!
In C1 use this formula, =IF((B1-A1)>=0, B1-A1, 1+B1-A1) for individual cells in column C, when you see that cells in column B has exceeded the 24-hour limit once. The duration in C1 should still show 1:31, but now the result when doing SUM over a range of cells in column C, like =SUM(C1:C2), will now show the correct and strictly additive sum. You can safely copy this formula to all cells in column C.
PS: cells in all of the columns can have Automatic or no formatting (which I think defaults to Automatic), if your time inputs look like the above. So you don't need to format all of those cells to Time or Duration. BUT remember to format the SUM cell to Format -> Number -> Duration.
PPS: if you are manually inputting the times (for for instance time tracking), then the easiest way to keep the much simpler =B1-A1 formula is to split the time up into two rows, like this:
A B C
23:39 0:00 0:21
0:00 1:10 1:10
Then the SUM of cells in column C still becomes 1:31.
I have pasted multiple run duration values from Garmin into a Google Sheet. The longer runs (> 1 hour) copy/paste correctly. Eg: 2:10:35. The problem is shorter (< 1 hour) runs. Eg 35:55. The latter are being shown in Google Sheets as 35:55:00. Ie Google assumes 35:55 is 35 hours and 55 mins, not 35 mins and 55 seconds. So for my shorter sub 1 hour durations I need an easy way to convert 35:55:00 to 0:35:55.
As Tom Sharpe said, there is some room for interpretation in the data you have. But assuming that the duration of your runs is always between 10 minutes and 10 hours, we can disambiguate the values as follows:
=if(A1 > 10/24, A1/60, A1)
Numerically, the duration values are measured in days, so A1 > 10/24 means "more than 10 hours". In this case the value gets divided by 60.
Depending on your workout regime you may want to replace the threshold of 10 by another number; perhaps it's safer to say that the runs are always between 5 minutes and 5 hours.
I have a cell formatted as a duration (6:49:00)
I want to convert that to an Integer of total seconds
This formula gives me the right number of seconds =C3*60
409:00:00 <-- But I want this as just 409
To convert duration to an integer expressing the number of seconds, use a formula such as
=value(A1*24*3600)
Time values are recorded so that 1 is one day. Multiplying by 24 (hours/day) and 3600 (seconds/hour) converts that to seconds. Then value makes it a number rather than duration.
Old answer, about formatting only.
You don't need any formulas to format duration as the number of seconds.
Go to Format > Number > More formats > More data and time formats
Delete the pre-filled format fields and add "Elapsed seconds" from the dropdown menu.
I have found this solution:
let the cell A1 filled with duration like 1:22:33, than formula
=HOUR(A1)*3600+MINUTE(A1)*60+SECOND(A1)
will do the trick.
For example, 1:01:01 -> 3661
=HOUR(A1) will NOT work if your hours in the duration is > 24 of course. So the last example is not correct.
What will work is the following.
Given: A duration in hours and minutes. eg 225:04 or 9:20 or 62:35
Format must be set as this (Elapsed hours:minutes)
=INDEX(SPLIT(A1, ":"), 0, 1)*60 + INDEX(SPLIT(A1, ":"), 0, 2)
