If you're trying to convert from a decimal fraction

of an hour into minutes, multiply by 60:



For example:



.77 hours = .77*60 minutes = 46.20 minutes



Of course, maybe you don't want "0.20" minutes,

but you can convert *that* by multiplying by 60:



.20 minutes = .20*60 seconds = 12.00 seconds.





Thus, 1.77 hours = 1 hour 46 minutes 12 seconds
