To calculate how many 16.9 oz bottles of water equal a gallon, we need to know how many ounces in a gallon first. According to the United States customary system, a gallon is equal to 128 fluid ounces.

1 gallon (US) = 128 ounces
1 water bottle = 16.9 ounces

Then, we divide 128 ounces by 16.9 ounces to calculate how many water bottles equal a gallon.
