Correct Time Sum, by Formulas. Help Please.
In Excel97, I have the following times i would like to sum.
(Minutes:Seconds:Seconds/100). A ------------- 1 07:56:07 ------------- 2 05:22:76 ------------- 3 05:14:84 ------------- 4 05:41:51 ------------- 5 05:14:01 ------------- 6 05:28:25 ------------- 7 07:56:37 ------------- ------------- 8 41:33:81 If i sum, i get 41:33:81, but the correct result for this case is 42:53:81 (Minutes:Seconds:Seconds/100). I would like the result to be in one single cell, that in this case is cell A8. What formula should i write in cell A8 ? Any Help appreciated. Robert. |

Bubu,
I did =SUM(A1:A7) and got 42:53.81 (sic!). You might want to format it as [mm]:ss.00 in case it goes over an hour. -- HTH Bob Phillips ... looking out across Poole Harbour to the Purbecks (remove nothere from the email address if mailing direct) "Bubu" wrote in message om...

Perhaps I'm just confused. I'm not sure how you're even displaying
05:22:76 much less using it to calculate hundredths of seconds. For me, that entry converts to 05:23:16. If your times are really in minutes:seconds:hundredths, then you're going to have to do some manipulation he First, if that's the case, your "correct result" should be 42:54:61, not 42:53:81. Second, XL doesn't understand hundredths of seconds using the colon - it interprets it as hh:mm:ss, where ss is base-60, not base-100. So you can never have a result where the last two digits are 60 or above. You could format your data as Format/Cells/Number/Custom [mm]:ss.00 and reenter your data as: A1: 7:56.07 A2: 5:22.76 .... A8: =SUM(A1:A7) == 42:54.61 and XL will display the (true) correct result. If you want to keep using hh:mm:ss to stand for mm:ss:hundredths, you can use this array-entered formula (CTRL-SHIFT-ENTER or CMD-RETURN): =SUM(INT(A1:A7*1440),SECOND(A1:A7)/100)/86400 which returns 42:54.61 when formatted as above.

Ah, well, in that case I was confused.
But in that case, why was the OP's SUM() off? Still confused. In article , "Bob Phillips" wrote: It is 05:22.76 (format is mm:ss.00) |

Don't know, it worked fine in my test, and Bubu hasn't posted back.
