How many ounces are in a gallon?

• 1 pint = 2 cups
• 1 cup = 8 fluid ounces

So if we multiply it out:

1 gallon = 4 quarts x 2 pints x 2 cups x 8 oz = 128 oz

Therefore, a gallon contains a total of 128 fluid ounces.

Why is a half gallon of milk 64 oz?

The reason a half gallon of milk is equal to 64 oz is because of how a gallon is defined in the US Customary System:

• A gallon contains 128 fluid ounces.
• To get half of any number, you divide it by 2.
• Therefore, half of 128 oz is 128 / 2 = 64 oz.

Is a 64 oz milk container really half a gallon?

Yes, any 64 oz container labeled as “half gallon” does in fact contain half a gallon of milk. However, there are a few things to note:

• Some 64 oz containers may be filled a bit over or under 64 oz due to production variance.
• Temperature affects liquid volume so cold milk takes up slightly less space.
• Some regions may define gallons differently so always check the total ounces.

But in general, a 64 oz milk container is intended to hold exactly half a gallon, which is the equivalent of 64 fluid ounces.

Does the size of the container affect the volume?

The size and shape of the container does not affect the actual volume of liquid it holds. For example:

• A half gallon bottle may be short and wide or tall and narrow.
• A half gallon jug has a handle while a carton does not.
• But both still hold 64 oz of milk.

The external dimensions of the containers can vary but the standardized internal volume will be 64 fluid ounces in both cases.
