Water is essential. We all need to hydrate, hydrate, and hydrate throughout the day to make sure our bodies’ daily water intake requirements are met every day. This is why water on the go has become more and more important to everyone and why bottled water has become increasingly available almost everywhere you go. Bottled water is available and can be bought in many places like **supermarkets, vending machines, local stores, gas stations,** and more.

This is also why, even more so than bottled water which has many **environmental concerns**, water bottles are now an essential part of every person’s everyday carry. Water bottles are sold everywhere and with good reason: People are looking for ways so that they can always tote water around and keep water with them anywhere and everywhere — and at the same time care for the environment!

A water bottle is an essential item to be able to meet our daily hydration needs. After all, we cannot stress enough the importance of keeping hydrated.

Here’s the thing: In order to stay healthy and fit, experts say that it is essential to drink at least half a gallon of water each and every day. So now begs the question: How many bottles of water is a gallon, exactly? And following that train of thought, how many bottles of water fill one gallon, and **how many bottles of water should you drink per day?**

## What Is A Gallon?

A gallon is basically a measurement of how much a fluid is. One gallon of water contains 128 ounces. Whereas one ounce is 1⁄16 of a US liquid pint and 1⁄128 of a US liquid gallon, or roughly 30 ml of a fluid. If you want to measure one gallon in ounces, you could multiply it with the 30 x 128 ounces and you get 3840. So one gallon of water has 3840 ml of water.

There are three measures that are all referred to as gallons. How do they differ, and which one are we using here?

### 1. Imperial Gallon

An imperial gallon is used to measure volume that is utilized in certain countries around the globe. **One imperial gallon is equal to 154 fluid ounces**.

### 2. Liquid Gallon

The liquid gallon refers to the US liquid gallon. It is the predominant gallon measure that is utilized in the United States and is most simply referred to as ‘gallon.’ **One US liquid gallon**, or** just gallon, contains 128 fluid ounces.**

### 3. Dry Gallon

**In the US,** one dry gallon is equivalent to 149 fluid ounces. This measurement dates back to colonial times and historically was utilized for the measurement of grain and not water. In present times, it is rarely used much.

## What Gallon Are We Using Here?

Since we are talking about liquids, more specifically water, then it is safe to assume that we are utilizing the predominant standard for measuring liquid — which is the US liquid gallon, which we will refer to moving forward more simply as the ‘**gallon.**’

### The Simple Formula

To answer the basic question of how many bottles of water fill a gallon, there are two main factors that we have to identify and establish. These factors are:

- How much water is in one gallon?
**How many ounces of water**can the water bottle hold?

Here is a simple method you can use to gauge how many of your water bottles are equivalent to one gallon of water:

**According to the US gallon system, one gallon of water is equivalent to 128 ounces.**

#### Step 1. Know the Ounces

The first thing you need to do is find out how many ounces are contained in the water bottle you are using.

#### Step 2. Divide This Number by 128

Because one gallon is equal to 128 ounces, in this sense, you should then divide 128 by the number of fluid ounces your water bottle holds.

#### Step 3. The Answer

The answer to this equation will give you the answer to your question.

Basically, the formula goes:

**Fluid ounces in one gallon ÷ fluid ounces in one water bottle = number of water bottles in a gallon.**

With his very simple formula in mind, you can easily calculate the number of water bottles of any size that will comprise one gallon of water.

## Water Bottle x Gallon Simplified Chart

As we all know, there are many, many different sized bottles that are available for purchase. This is to accommodate people’s differing needs and wants when it comes to finding the right water bottle for them. Using the above formula, here’s a simple way to quantify the number of water bottles that make up one gallon of water.

- 1 gallon of water is equal to 15 bottles at 8 oz each (1 glass)
- 1 gallon of water is equal to 7.5 jugs at 16 oz each (1 half quart)
- 1 gallon of water is equal to 7.1 containers at 16.9 oz each
- 1 gallon of water is equal to 4.61 containers at 26 oz each
- 1 gallon of water is equal to 3.75 jugs at 32 oz every (1 quart)
- 1 gallon of water is equal to 3.55 jugs at 33.8 oz every (1 liter)

Basically, the number of water bottles that make up one gallon just depends on the size of the water bottle in question.
