🔥 🔥 🔥 It all depends on the size of the water bottle ❗ ❗ ❗

The specific calculation is as follows:
1. US standard gallon = 128 US ounces
2. Common water bottle capacity conversion:
⭕ 16.9 ounces (the most common disposable plastic bottle, equivalent to 500 ml):
▪ Bottles per gallon = 128 ÷ 16.9 ≈ 7.57 bottles
▪ So, 1 US gallon is approximately equal to 7.5 standard 16.9 ounce water bottles (daily drinking water goals are usually simplified to 7 or 8 bottles)
⭕ 20 ounces (common sports water bottles):
▪ Bottles per gallon = 128 ÷ 20 = 6.4 bottles
▪ It takes about 6.4 20-ounce water bottles to make up 1 gallon
⭕ 33.8 ounces (common 1-liter water bottle, note: 1 liter = 33.814 ounces):
▪ Bottles per gallon = 128 ÷ 33.8 ≈ 3.79 bottles
▪ It takes about 3.8 1-liter bottles to make 1 gallon
⭕ 8 oz (small bottle/glass):
▪ Bottles per gallon = 128 ÷ 8 = 16 bottles
▪ It takes exactly 16 8-ounce bottles to make 1 gallon

General points:
Most common 16.9-ounce bottles: about 7.5 bottles = 1 US gallon
