convert military time to regular hours

[Kathy]

I would like to covert military time to regular hours - (i.e 1.50 hrs to 1
hour 30 minutes) and also keep track of the average time it takes to finish a
task -

(i.e.
1 task could take 1.25 or
1 task could take 2.50 hours

I would like to be able to show "on average" how long it takes a task to be
completed.

Thanks,
Kathy

Hi Kathy

Excel stores times as fractions of a day (24 hours). So to convert your
1.5 hours to 1:30, divide by 24 and
Format>Cells>Custom> hh:mm:ss

To get the average with 1:15 in B1 and 2:30 in B2 simply enter
=AVERAGE(B1:B2) to return 1:52:30
