32 gal/min = qt/h
32 gal/min * (60 min/ hr) * (4 qt/gal)
= 7680 qt/hr
notice that I multiply by things that are the same top and bottom but different units
60 min = 1 hr
4 qt = 1 gal
I do the numerator and denominator to make the units I want to get rid of cancel and leave the new ones that I want.
for example 5 feet, I want inches
5 ft * (12 in / 1 ft)
ft cancels
left with 60 inches
32gal x 60min x 4qt = 7,680qt
1min x 1hour x 1gal = 1hour
32 gal x 60 min x 4 qt = 7680 Qt
1 min x 1 hour x 1 gal = 1 hr
