It is a bit stange to ask how many gallons -- plural -- are in a cup, because the gallon is a larger unit of measure than the cup. We usually think of cups per gallon. But no matter. Since there are 16 cups per gallon, we can say there is one gallon per 16 cups. But that sounds silly, because having a number in the denominator -- 16 in this case -- is not cool, so we need to get rid of it. Since 1/16 = 0.0625, we can say there is 0.0625 gallon per cup, instead of saying one gallon per sixteen cups.
