convert hours to minutes

[Guest]

I have a time number 1:19:00 (One hour and 19 minutes) that I want to convert
into minutes (79). How can I do that?

TY

Convert or display? Display then just use custom format [mm]
if convert multiply with 1440 and format as general

Thank You, It worked perfectly for 1:19:00 but for 10:42:00 it did not work.
Any idea why?

Some additional information. I am determing how much time is available to
star gaze per night. I am doing this by looking at the difference in the end
of civil twilight in the evening and the beginning of civil twilight the next
morning. This gives me the amount of time available to star gaze on that
night. I am looking at Sunday night and the following Saturday night. I
then take the two times 10:42:00 and 10:24:00 for example and add them
together and divide by 2 to get an average for the week. I now want to
convert that average number 10:33:00 to minutes and then multiple by 7 to get
the total minutes available.

Multiplying by 1440 should work in all cases but it is not. Any ideas as to
way?

Works for me, if I multiply 10:42:00 with 1440 (10 hours 42 minutes right?)
I get 642 minutes,
what do you get? Remember to format as general or else you get a pseudo time
format
