A gallon is equivalent to 128 fluid ounces. The number of water bottles in a gallon depends on the size of the water bottle. Here are some common examples:
-
16.9-ounce (500 ml) water bottle:
128 ÷ 16.9 ≈ 7.57 bottles (about 7 and a half bottles) -
12-ounce water bottle:
128 ÷ 12 ≈ 10.67 bottles (about 10 and two-thirds bottles) -
8-ounce water bottle:
128 ÷ 8 = 16 bottles
Summary:
Bottle Size| Bottles per Gallon
---|---
16.9 oz| ~7.5
12 oz| ~10.7
8 oz| 16
