Drinking water is a vital resource for preppers, as it is essential for drinking, cooking and sanitation. Knowing how many gallons are in a 24 pack of water can help you plan your emergency preparedness supplies. But what exactly does this number mean? How many water bottles equal one gallon?


How Many Water Bottles Equal a Gallon?

How many bottles of water equals a gallon really depends. As you may know, there are several different sizes of water bottles that are sold. The common sizes are 8, 12, 16.9, 20, 24 and 33.8 fluid ounces.

There is 128 fluid ounces in a liquid gallon. So, to calculate the number of water bottles to equal a gallon you would use the following formula:

128 fluid ounces divided by the size of the water bottles you have stored.

We’ve already done the math for you.

  • 16 (8-ounce bottles) equals a gallon
  • 10.5 (12-ounce bottles) equals a gallon
  • 7.5 (16-ounce bottles) equals a gallon
  • 6.5 (20-ounce bottles) equals a gallon
  • 5.5 (24-ounce bottles) equals a gallon
  • 3.75 (33-ounce bottles) equals a gallon

It’s important to remember that the size and capacity of each bottle may vary slightly depending on the brand so make sure to read the labels carefully before purchasing any type of bottled water product.

How much does a gallon of water weigh?

Depending on whether you plan to bug in or bug out, the weight of water needs to be factored into your emergency plan. If you plan to bug out, it may be better for you to have the bulk of your water cached at your retreat location.

Depending on where you live, the weight of water per gallon will vary. Americans generally use the US gallon while others us the imperial gallon, or UK gallon.

One US gallon of water weighs roughly 8.34 pounds.

One UK gallon of water weighs around 10 pounds.

As you can see, water bottles or cans of water can add up to a lot of weight. Traveling with bulk water storage is taxing and a waste of space.

If you’re staying in place, you will still need to consider where you’ll store it and make sure you spread out the load if on elevated floors.

Tips on how to store your Water Bottles.

When storing cases of water bottles, it is important to keep them away from direct sunlight and out of heat-generating areas such as near furnaces and air conditioning units. Keeping your supplies in a cool, dark place will help ensure that your drinking water remains safe for consumption.

Additionally, make sure that there is adequate ventilation around the stored products, so they don’t become too hot in the summer months.

It is also important to rotate through your stock regularly – at least once every 6 months – so that all bottles remain fresh. This is especially important with plastic bottles, as they can start to degrade over time and expose the water to contaminants.

Cases of bottled water usually have inner packaging made of cardboard or plastic wrap. To keep your water supplies fresh longer, you should remove this wrapping before storage if possible. It also helps deter any pests from getting inside and contaminating the bottles. If you have to keep this packaging on, make sure it is sealed tightly with tape or rubber bands.


When stacking up cases of water bottles, it’s best to place them on shelves or pallets if possible. This will help spread out the weight and prevent cases from falling over if bumped or moved around. Make sure to use a stable basis like wall studs when installing shelves for additional support.

Additionally, ensure that your shelving is appropriately sized for the cases so that they don’t sag or become misshapen after some time in storage.

Finally, label each case with its expiration date before placing it into storage so that you know which ones need to be used first and can rotate through your supplies efficiently. Additionally, keep a list of the bottled water in each case to stay organized and monitor changes in inventory.

By following these simple tips, you can easily store large numbers of water bottles correctly and be ready for any emergency situations that may arise.

By taking the extra steps to properly prepare your stored water bottles, you can rest assured knowing that your family will have access to safe drinking water during an emergency.

Storing cases of bottled water is one of the most important tasks when prepping for disasters or other unforeseen events, so make sure to follow these guidelines and stay prepared.
