Question: 2 gallons is how many bottles of water?
Answer: In that case there would be 10.663 bottles per gallon. If, on the other hand, you can still find a beverage bottler who deals in Imperial units of measurement, there would be 16 half-pint bottles or 8 pint bottles in a gallon, and thus 4 quart bottles or 2 half-gallon bottles in a gallon.
