Without a macro, you can't just type in 109 and have that same cell display 1:49. To display the number of seconds in time as you want, use a formula in another cell to convert for you.
Macropod's formula will work fine. Now this is just personal preference, but I would divide by 86400 instead of 1440. How'd I come up with 86400? That's (
60 seconds in a minute *
60 minutes in an hour *
24 hours in a day) = 86400.
So 109/(60*60*24) = 109/86400 = 0.001261574 = 1 minute 49 seconds.
If you type 109 in A1, then in any other cell, you could type in [COLOR=blue white]=A1/86400[/color]
Format the cell containing the formula as either
hh:mm:ss or
[m]:ss to display the time the way you want. You can format the cell by
[ul][li]Right click[/li]
[li]Choose Format Cells[/li]
[li]Choose
Custom from the list on the left[/li]
[li]Type in one of the formats above in the box on the right[/li][/ul]
Still have questions about how the heck Excel deals with times? Then see
SkipVought's FAQ entitled
Why do Dates and Times seem to be so much trouble?
Good luck!
