Rather, the most important thing is the amount of water you bottle and the size of a gallon.  
For example, with a 20-ounce bottle, you need 128/20 = 6.4 bottles.  
(This assumes you use 128 oz US gallons. If you have imperialist gallons, 153.7 oz requires 7685 bottles. And so on with liters of different definitions and sizes).
