How Many Water Bottle is in a Gallon of Water? Learn With Us!

Unit-conversations might seem difficult to you. Especially when you intend to drink a certain amount of water or the water that might serve a specific purpose, you will need to know the exact volume. But there are some ways to easily calculate the volume, no matter how big it is.

If you are confused with ounces, liters, and gallons, then this article will help you to calculate the numbers and figure out how much is the exact volume you need.

Fluid Ounces in a Water Bottle

When talking about fluid ounces, the first thing that might come to your mind is the rule of drinking 8 x 8 ounces of water a day. Drinking 8 ounces of water eight times a day is one of the most widely adopted drinking habits to people all over the world. But the thing is, how to measure the fluid ounces?

The easiest way would measure it through half a liter water bottle. There are approximately 16.9 ounces of water in a 500ml water bottle. You can find a 500ml water bottle easily almost everywhere. So, next time if someone asks you, how many fluid ounces in a water bottle? It will not be an issue for you to convert the volume into ounces to half a liter water bottle, and vice-versa.

To be more frank, which of these two is more convenient for you to mention? Do you feel better uttering 500ml rather than 16.9 fluid oz? Mostly, yes. So, why do they even use 16.9 fluid oz as a volume which sounds more complicated? Well, the fluid ounce is the value of U.S. customary units. Yet, you will find certain people who find convenient to use fluid oz because of fair trade laws in the U.S.

It is worth mentioning that fluid ounce is part of the imperial and U.S customary volume units.

16.9oz Bottles in a Gallon

Now, the volumes get bigger. We are not dealing with fluid ounces or ml anymore. Gallon is the imperial customary volume unit for the U.S. As we have previously mentioned, the 16.9oz bottle is also known as 500ml in the metric system. According to U.S. standard, 1 gallon stands for 128 fluid oz.

Therefore, if you want to know, how many 16.9 fl oz bottle in a gallon? Then simply divide 128 by 16.9. And that would be 7.57 water bottles of 16.9 fluid oz in order to fill a gallon. Looking for a more rounded figure? Consider it to be 7 and a half or 8 bottles of water, as you cannot have a water bottle of .57 liter.

Let’s calculate this practically. If you are to drink a gallon of water per day, you need to drink 16.9 fluid ounces of water 7.5 times. To round it up, you would need to drink 3.785 liters of water throughout the day.

As for the U.K. standard is concerned, 1 gallon is equivalent to 160 fluid oz, which is 4.546 liters of water. Meaning, you would need 9.46 bottles of water to fill a gallon. Consider this to be 9 bottles or a little less than 9 and a half bottles. As you can see, when calculating how many bottles of water is a gallon – the answer changes significantly when you move across the pond.

People use gallons in order to carry a significant amount of liquid. But you might face a situation where you will need a gallon of water without a rightly measured container for filling a gallon. In cases similar to this, you will have to weigh the volume of water in fluid oz or maybe in liters.

NOTE: the manufacturers recommend that the users avoid filling the bottles with any carbonated beverages as this may erode paint. However, if you skim over the reviews you will see plenty of users saying they have kept carbonated beverages inside the bottle for a period of time and nothing has happened. It’s better to believe the manufacturers, however, do as you wish and see for yourself.

Tips for the cleaning and maintenance:

Although dishwasher use in case of this water bottle is safe and many users have clarified that it is indeed safe to clean them inside the dishwasher, the manufacturers recommend hand cleaning with soap. The soap can be diluted in warm water for improved material preservation (particularly the cap). Alternatively, if you want to avoid chemical cleaning (unless the soap is vegan, made out of natural materials) you can use a pinch of salt, baking soda or vinegar.

After you are done cleaning, rinse it out with a warm water and keep it exposed and empty. You can leave it out on any dry spot or out in the sun. Do not, in any case use a microwave to either hit a beverage inside of the bottle or dry the freshly cleaned one. Furthermore, it is not recommended that you keep it inside the freezer. If you want your beverage to maintain its cold temperature just pour the frozen beverage inside the bottle do not pour a room temperature or hot beverage and put it inside the freezer.

Both of these activities will damage not only the water bottle but the quality of your beverage making it harmful for consumption. This is because of the chemical reactions between the beverage and the material with which the water bottle is made out of. Remember that the exchange of an extremely high to low (or the other way around) temperature works like a catalyst and affects the health of the beverage that is kept inside the water bottles.

The flow is simple

The wide mouth enables water to flow out while you’re on the road, keeping you hydrated. The double-walled vacuum-insulated water bottle is simple to fill and clean. The bottle will not sweat even when filled with ice.
