Being stuck halfway through a recipe without the right conversion can be quite frustrating! To have you prepared for your next baking session in the kitchen, you should know some basic conversions first.

How many cups of milk are in a gallon? There are 16 cups of milk in one gallon, and it is the same for water and other liquids. However, it helps to keep in mind that the amount of cups per liquid gallon is different from the number of cups per dry gallon, and these should not get confused.

Below is all you need to know about converting gallons to cups and back again, to ensure you aren’t stuck halfway through baking again!

How Many Cups In A Gallon

There are 16 cups in a liquid gallon, and this covers almost all liquids, such as milk and water. The number of cups per dry gallon, such as for flour, differs from this.

Here is a table that illustrates this:

1 gallon of milk16 cups
1 gallon of water16 cups
1 dry gallon18.6 cups

To make a gallon, you would need 16 cups of milk, which also works out to 3.79 liters. It is probably much easier for you to measure out 16 cups than to measure 3.79 liters, which can be a little tricky.

A US gallon measures 3.78 liters, whereas an imperial gallon measures 4.54 liters. This is quite a substantial difference, which is why it is so important to be sure of the type of gallon a recipe is calling for.

As shown above, a US liquid gallon is equal to 16 cups. An imperial gallon is equal to 18.18 cups.
