A time is a fraction of a day. A day in excel = 1. Half a day = 0.5. To
convert to hours simply multiply by 24. To convert to minutes simply
multiply by 24 and then multiply by 60.

Hi there, I was wondering if anyone has any suggestions on how to convert
a
time format (e.g. hh:mm:ss - 00:16:50) into time in actual minutes (which
in
this example would be a total of 16.8 minutes). I have an incredible
amount
of data to convert, so any suggestions would be greatly appreciated!
Many thanks!
