Formating a Time Calculation Result
Hi all, I have created a button called TIME with the
following macro attached: Sub takeoff() Dim stringval As String stringval = Format(Now(), "h:mm") ActiveCell.Value = stringval End Sub If I select A1 and click on this button, it will put the current time in A1. A few minutes later I click on B1 and the TIME button and I get that cuurent time. In C1 I have the calculation =B1-A1 which gives me the minutes difference (ex: 10:15 10:47 result :32) What I need is to change C1 to tenths of an hour. 1-6 minutes = .1 hr, 7-12 minutes = .2 hr, and so forth. Any suggestions on how I can do this? I've tried just dividing C1 by 6 which doesn't work, tried formating but am not sure I am picking a correct custom format, etc. Help please. |

Formating a Time Calculation Result
XL stores times as fractional days, so to get hours, multiply by 24:
C1: =CEILING((B1-A1)*24,0.1) This will work as long as your times don't span midnight. If they do, you have to compensate for time resetting to 0 at midnight: C1: =CEILING(((B1-A1)+(B1<A1))*24,0.1) or C1: =CEILING(MOD(B1-A1,1)*24,0.1) In article , "COG" wrote: Hi all, I have created a button called TIME with the following macro attached: Sub takeoff() Dim stringval As String stringval = Format(Now(), "h:mm") ActiveCell.Value = stringval End Sub If I select A1 and click on this button, it will put the current time in A1.

Formating a Time Calculation Result
Your solution is getting me close, but didn't quite do
it. Cells A1 and B1 are formated as h:mm, and I had 10:19 and 10:32 in them respectively. When putting in your formula for cell C1, I got 7 which doesn't make sense. I was under the impression Excel stored the date/time as a serial number and that is what is messing me up. Any other suggestins?

Formating a Time Calculation Result
Dates *are* integer offsets from a base date. Times are any fractional
remainder, so 3 July 2004 13:05 is stored as 38171.54514 (1900 date system) or 36709.54514 (1904 date system). In any case, the 0.54514 represents (13 + 5/60)/24. But your macro places only the times in the cells, so the date serials don't matter. Your result of 7 makes no sense to me either. All of the formulae I gave you return 0.3 for me, which meets your specifications. In article , wrote: Your solution is getting me close, but didn't quite do it.
