I have an assignment to audit the time it takes convert a printing press from one job to the next. I've been using a watch to take the readings in hours, minutes, and seconds.

I recorded them in my spreadsheet, as h:mm:ss, but it showed a date also. I think I finally got that resolved, but now, when I try to subtract one time from another time, I get an incorrect answer. I think I need to convert all of these times into decimals, as in 13.23.44, as oppossed to 13:23:44.
One post on page 1 of my search said to multiple A1*24, but I don't fully understand. I tried that, but 11:30 became 11.50?
I need to extract the set up time, or job to job changover time in a decimal format if possible. There are other tasks being done with those numbers later in the spreadsheet that are more conducive to decimals, than the time format.......
