How do I get time elapsed in terms of minute?
I cannot, for the life of me, figure out how to make a cell read time in
total minutes. I am trying to read the amount of time elapsed in minutes. For example, I start running a sample at 18:32 (24 hour clock) and stops at 21:43. I can get Excel to calculate the difference to 3:11 (3 hours and 11 mins) but I need it in terms of minutes (191 mins). I also cannot find out how to get excel to calculate time elapsed of any kind if it changes days. For example, if I start a sample at 22:32 and it ends at 01:43 (once again 191 mins) excel gets confused. |

How do I get time elapsed in terms of minute?
Try this:
=((A2-A1)*60)*24 A2 is the date/time for end and A1 is date/time for beginning "Mcspore" wrote: I cannot, for the life of me, figure out how to make a cell read time in total minutes.

How do I get time elapsed in terms of minute?
Assuming start time is in A1 and finish time in B1. You need to know
that Excel stores times as fractions of a 24-hour day, so 12 hours is stored internally as 0.5, 6 hours as 0.25. Thus, any answer you get which is in Excel time format needs to be multiplied by 24 and by 60 (and the cell formatted as number) if you want it to be in minutes. Further, in the situation where the start time appears to be larger than the finish time because you have gone through midnight, you need to add 1 to any subtraction of the times to account for this. So, this leads to (one of many ways of doing it): =IF(A1B1,B1-A1+1,B1-A1)*24*60 Format the cell as General or as Number. Hope this helps.

=IF(J1K1,(K1+1-J1)*24*60,(K1-J1)*24*60) J1 is start time K1 is end time formatted as general normally a general format time result gives you part of a day thats why you have to multiply by 24 and 60 to get minutes the "if" formula part will ensure you get the right result when times fall passed midnight Bill K Greetings from New Zealand "Mcspore" wrote in message ...

Mcspore,
Try this: Column B Column C Start End Lapse 54 12/8/07 18:32 12/8/07 21:43 =(((C54-B54)*86400)/60) 55 12/8/07 22:32 12/9/07 1:43 =(((C55-B55)*86400)/60) Both these give you 191 minutes. Make sure format cell B54, C54, and all others as Date and Time. HTH Dennis "Mcspore" wrote: I cannot, for the life of me, figure out how to make a cell read time in total minutes.

Or you could try this: Start A1 End B1 Lapse C1 A1=Date and time B1=Date and Time C1=((B1-A1)*1440) hth "Mcspore" wrote: I cannot, for the life of me, figure out how to make a cell read time in total minutes.

.... or (somewhat shorter) =MOD(K1-J1,1)*24*60

Thanks David,
So why does it work? Never seen this one before.

From -18:00, the formula =MOD(-0.75,1) will return 0.25 which is 06:00.
The other useful simplification of your formula is =(K1-J1+(J1K1))*24*60 which works because the boolean TRUE or FALSE from (J1K1) is evaluated as 1 or 0. -- David Biddulph "Bill Kuunders" wrote in message ...
