3 situations would be as follow, i set the formular like this is =IF(B1<A1,
24/24-A6+B6,B6-A6), both A & B using time format and C using number format.

A B C
Start Time End Time No. of hours
10:30 15:00 4.5
00:00 08:00 8.0
08:00 23:59 16.0 **Problem**

I can get the result for the first 2, but not the last one, any one can
help, many thanks!

What's the problem?

4.5
8
15.98333


is what I get using

=(B1-A1+(A1B1))*24

are you saying that you want to round, if so what's the rounding criteria?
Nearest .25 using decimal hours? If so

=ROUND((B1-A1+(A1B1))*24/0.25,0)*0.25

will return 16

Hi!

Try this:

=(B6-A6+(B6<A6))*24

Copy down as needed.

Returns:

4.5
8
15.9833333333333

Yup, that is what i am looking for the rounding problem, and it works
perfectly would you explain a little bit the logic behind, many thanks!
