The operator should have been '<', not '':

=round((A1+if(b1<a1,1,0)-b1)*24,2)

Thank You for a quick response. Unfortunately this did not work

A1= Start Time 18:00
B1= Finished Time 18:30
c1=ROUND((A1+IF(B1A1,1,0)-B1)*24,2)
result in C1 was 23.5 where it should be 0.5

our company works with iso standards.we need to put in our start time and
finished time ( in 24 hour format ). The shifts start at 06:00 and finishes
at 18:00, but this is when the next shift starts 18:00 to 06:00.

A1=Start Time B1= Finished Time C1 = Actual Time
23:00 01:24 2.4

iso standards 1 unit = 6 minutes

i found one thread that show this formulaa which works up to midnight but
after that it don't

=Round((A1-B1)*24,2)

any help on this matter or any direction is greatly appreciated and Thank
You in advance.
