Recipes can be tricky with measurements in gallons, quarts, pints, and cups. How many cups in a gallon? What about the other way around? It can be helpful to know how to make conversions between gallons and cups while cooking or baking.

You are probably familiar with the size of a gallon of milk and with the size of a measuring cup, but you may not know how many cups are in a gallon. One gallon equals 16 cups. So if you’re baking something and a recipe calls for 1 gallon of an ingredient, you will need to use 16 cups of that same ingredient.

Converting from gallons to cups is useful when scaling recipes up or down. If a recipe calls for 4 cups of an ingredient and you want to quadruple the recipe, you will need 16 cups which is equal to 1 gallon.

**How Many Cups in a Half Gallon?**

The conversion from gallons to cups can be helpful when making recipes that require large amounts of ingredients. For example, let’s say a recipe calls for a half gallon of cream. To make this recipe with an 8 fluid ounce measuring cup, you would need 8 cups (16 cups divided in half). So there are 8 cups in a half gallon.

**Converting Between Cups and Gallons**

The conversion factor between cups and gallons is 16 cups per gallon. You can convert from cups to gallons or gallons to cups by multiplying or dividing by 16.

### Gallons To Cups

To convert gallons to cups, you multiply the number of gallons by 16.

Number of cups = Number of gallons × 16

For example, if you want to know how many cups are in 2 gallons, you multiply 2 by 16.

Number of cups = Number of gallons × 16

Number of cups = 2 × 16

Number of cups = 32

So, there are 32 cups in 2 gallons.

### Cups To Gallons

To convert cups to gallons, you divide the number of cups by 16.

Number of gallons = Number of cups ÷ 16

For example, if you want to know how many gallons are in 8 cups, you divide 8 by 16.

Number of gallons = Number of cups ÷ 16

Number of gallons = 8 ÷ 16

Number of gallons = 0.5

So, there is 0.5 (½) gallon in 8 cups.
