# Does 64 oz equal a half gallon?

The quick answer is yes, 64 fluid ounces does equal a half gallon. Let’s take a deeper look at the relationship between ounces and gallons to understand why.

## Understanding Ounces and Gallons

First, it’s helpful to understand the definitions of ounces and gallons:

• An ounce is a unit of volume typically used for measuring small amounts of liquid. 1 fluid ounce = 29.57 milliliters.
• A gallon is a larger unit of volume typically used for measuring larger amounts of liquid. 1 US gallon = 128 fluid ounces = 3.785 liters.

There are two key points that explain the relationship between ounces and gallons:

1. There are 128 fluid ounces in 1 gallon.
2. A gallon can be divided into halves, just like any other quantity. So half of 128 fluid ounces is 64 fluid ounces.

Looking at those two facts, we can conclude that 64 fluid ounces equals half of the total 128 fluid ounces in a full gallon. Or in other words, 64 fluid ounces equals a half gallon.

## Breaking Down the Arithmetic

We can also look at the arithmetic to further prove that 64 fluid ounces equals a half gallon:

• There are 128 fluid ounces in 1 gallon
• To get half of something, you divide by 2
• 128 fluid ounces divided by 2 equals 64 fluid ounces

So if we take a gallon and divide it into two equal parts, each half equals 64 fluid ounces. Going through the math step-by-step clearly shows that 64 fluid ounces is equal to a half gallon.

## Examples of 64 fluid ounces
