I have 2 cells (f4 & g4) , with format in hh:mm. When use a formala f4-g4
in
a 3rd cell it gives me the difference of hrs between the 2 cells. But If I
want to apply some calculation on the 3rd cell it does not work.
Example f4 - g4 gives me 13:00 and in cell h4 my formula is (f4-g4)*2. The
answer I get is 2:00. I want the answer 26:00.
Can you please advise, How can I do this.

Thanks
