I need to add a long list of minutes and seconds. (ex. 25:16, 16:39, 27:41)
I have looked at all the functions and cannot find one that works. They all
want to add the times assuming they are hours and minutes or time on a clock.
I want to find a function that would add up the previous example and display
it as 69:36 total minutes and seconds. It seems like one of the problems I
am running into is finding or creating my own function that knows to add up
the seconds to 60, not 100 like most decimal functions are used to. Does
anyone have an answer? I would be forever grateful!

You need to enter 0 for hours like

0:25:16

how else would excel know it is not 25 hours?
Finally use a custom format of [mm]:ss or else
you won't get the right display

Emily,

Using any formula to add time values works fine in Excel. I think the
problem in your situation might be that when you enter in the format xx:yy,
Excel assumes hours and minutes, not minutes and seconds. Since both are
multiples of 60, this should work fine, except when the total hours exceeds
24, in which case Excel would want to roll over to another day after 24
hours, not 60. You can force Excel to interpret xx:yy as mm:ss by entering
it in the form 0:xx:yy, if you're willing to do all that keying. If not,
and if my presumption that Excel has assumed hh:mm for your mm:ss is
correct, post back with some specific examples of what you're trying to do,
and I might be able to suggest other workarounds.

Well, you just add them up, and format them properly.

The only issue I see is that, if the values are truly entered as you post, then
Excel will be interpreting the input as hours:minutes rather than
minutes:seconds.

There are a variety of methods of dealing with this problem.

If all the entries are in the same format, merely SUM them and divide by 60.
Format the result either as [m]:ss or [h]:mm:ss

The brackets around the h or the m keeps them from "rolling over" at 24 hrs or
60 minutes.

For example, if your values are in column A:

=SUM(A:A)/60

Format as one of my two suggestions.


--ron

Enter the numbers with a 0 for the hour like so...
0:25:16
0:16:39
0:27:41

and use a custom format like so...
[m]:ss

you can them use a normal sum() function (or any arithmetic function) like
so...
=Sum(A1:A3)
or
=A1+A2+A3

and use the same custom format to get a result like...
25:16
16:39
27:41
69:36

Hi Emily16

This site may help you http://www.cpearson.com/excel/datearith.htm

Below is an extract:

If you want to add up minutes and seconds, you must include a leading
"0:" in your data. For example,
enter "0:10:20" to indicate 10 minutes, 20 seconds. When you sum these
times, Excel will display the
sum in "time-of-day" format, meaning that adding 0:40:10 and 0:30:20
will yield 1:10:30. You can prevent
Excel form "rolling over" at the hour by formatting the result cell as
[m]:ss which will cause it to
display 70:30 rather than 1:10:30.
