mm:ss formatting

[levy77]

Does anyone have a solution to formatting mm:ss without the AM/PM after it. I'm creating a spreadsheet where I need to put time as an input, say for a race where something like 10:30 would be 10 minutes and 30 seconds. There are then some calculations done on the time which says if time is below 10 minutes the person gets 20 points, if above 20 minutes the person gets 0 points then uniformly distributed for all other values between 10 and 20 minutes. The cutoff points will also be dynamic, so that you could change the lower bound to something like 12:30, which would be 12 minutes and 30 seconds.

Is there also a way once the formatting is correct, to apply data validation so that the person must enter mm:ss exactly?

This sheet will be spread to a large number of different computers so I wont be able to just change the computers default time setting as this will be redundant when other people open the sheet.

Does anyone have any suggestions or direction?

Cheers.

To format - Right click on cell, select Format Cells, select custom, enter mm:ss

I've tried that, with that formatting, I put in 10:00, the result was the cell showed 30:00 and the value in the formula bar was 10:30:00 AM and the actual value was 0.44.

maybe

I forgot to say you need enter full time format:
00:10:30
00:125:15

Hi Sandy, I have seen a solution similar to this but my system doesn't seem to like it, got any ideas?
For this one i entered 00:10:30.

No, this is NOT convert hours to minutes
as I said you need to enter 00: then minutes and seconds 10:30 or 125:15 (as in post#5)
but not 02:15:25

you need proper minutes and seconds in cell not in formula bar so you have it
formula bar doesn't matter in this case

[mm]:ss is a custom format

I entered 00:10:30, 00 hours, 10 minutes, 30 seconds. I used the [mm]:ss format and the output I got was that in the formula bar.

you need to test it
as you can see I entered 00:10:30 and got 10:30 in the cell but 00:10:30 in formula bar
I don't know how US style works (maybe change it in regional setting to normal without idi*** AM/PM) and use 24-hours clock

Thanks for your help, I ended up formatting as text then pulling the values using left and right.
