Is 24 oz 3 cups?

Determining equivalent measurements between ounces and cups is a common need when cooking or baking. Specifically, when a recipe calls for a certain number of cups, it’s helpful to know how many ounces that equals. So is 24 ounces the same as 3 cups? Let’s take a closer look.

The Answer

Yes, 24 fluid ounces is equal to 3 cups. This equivalency applies to volume measurements of liquid ingredients. Here’s a breakdown of the conversion:

  • 1 cup = 8 fluid ounces
  • 24 fluid ounces ÷ 8 ounces per cup = 3 cups

So 24 fluid ounces contains the same volume as 3 cups. This can be useful when substituting ingredient amounts in recipes.

Converting Between Cups and Ounces

Knowing how to convert between cups and ounces is handy for cooking and baking. Here are some key equivalencies to remember:

  • 1 cup = 8 fluid ounces
  • 1 fluid ounce = 2 tablespoons
  • 16 tablespoons = 1 cup
  • 1 cup = 16 tablespoons

So 8 fluid ounces equals 1 cup, which is the same as 16 tablespoons. And 1 fluid ounce equals 2 tablespoons. Using these conversions, you can figure out any combination of cups, fluid ounces, and tablespoons.

Ounces to Cups

To convert fluid ounces to cups:

  1. Divide the ounces by 8 (since there are 8 ounces in 1 cup)
  2. The result is the number of cups

For example, 48 oz ÷ 8 oz/cup = 6 cups

Cups to Ounces

To convert cups to fluid ounces:

  1. Multiply the number of cups by 8 (because 1 cup = 8 fluid ounces)
  2. The result is the total number of fluid ounces

For example, 3 cups x 8 oz/cup = 24 fluid ounces

Tables for Conversion

For easy reference, here are some tables showing conversions between cups, fluid ounces, and tablespoons:

Cups Fluid Ounces Tablespoons
1 cup 8 ounces 16 tablespoons
2 cups 16 ounces 32 tablespoons
3 cups 24 ounces 48 tablespoons

Fluid Ounces Cups Tablespoons
8 ounces 1 cup 16 tablespoons
16 ounces 2 cups 32 tablespoons
24 ounces 3 cups 48 tablespoons

Examples of 24 oz Equaling 3 Cups

Here are some examples that demonstrate the equivalency of 24 fluid ounces and 3 cups:

  • A recipe calls for 3 cups of milk. You could measure out 24 fl oz of milk instead.
  • If you need to substitute 24 fl oz of buttermilk for 3 cups called for in a recipe, you can make a direct substitution.
  • A protein shake recipe says to blend 24 oz of almond milk. You could measure out 3 cups of almond milk to get the same amount.

No matter what type of liquid you’re measuring, 24 fluid ounces will give you the same volume as 3 cups.

Why Equivalent Measurements Matter in Baking

Using precise measurements, especially with liquids, really matters in baking recipes. Because baking relies on chemical reactions, the proper proportions of ingredients are critical. Even small variations can cause a recipe to fail. That’s why many baking recipes will specify fluid ounces or cups of liquid ingredients instead of general terms like a “small carton.”

With liquids like milk, buttermilk, cream, and oil, slight changes in the volume used can negatively impact the chemistry in baked goods. The conversion between cups and fluid ounces provides standardized units of volume so recipes work as intended.

Examples of Liquid Measurements in Baking

Here are some examples of why using the right liquid volume is important in baking recipes:

  • Pancakes: Using 1 cup (8 fl oz) of milk versus 1 1/4 cups (10 fl oz) will cause a difference in pancake texture.
  • Cakes: Adding 1/2 cup (4 fl oz) vegetable oil instead of 3/4 cup (6 fl oz) changes the moisture and richness of the cake crumb.
  • Cookies: A substitution of 6 tbsp (3 fl oz) milk instead of 1/4 cup (2 fl oz) buttermilk will affect spreading and crispness.

So while you may be able to take more liberties with liquid volumes in cooking, baking relies on accuracy for best results.

Tips for Measuring Cups and Ounces Precisely

To get the most accurate measurements of cups and ounces:

  • Use measuring cups and spoons. Don’t estimate amounts or “eyeball” volumes, especially with viscous liquids like oil or honey.
  • Use appropriate cup measures. Use liquid measuring cups with spouts for liquids, and dry measuring cups for dry ingredients.
  • Read at eye level. Place measuring cups on a flat surface and read the volume marking at eye level for greatest accuracy.
  • Don’t overfill. Liquids shouldn’t go over the very top marking of the cup for an exact measurement.
  • Level off. Use straight edge of a knife or spatula to level off dry ingredients even with the top of the measuring cup.

Adhering to these best practices for measuring ensures you are getting the correct volumes called for in recipes.

The Difference Between Fluid Ounces and Ounces by Weight

It’s important to note the difference between fluid ounce measurements versus ounces by weight. The conversion to cups only applies to fluid ounces in volume amounts. Ounces measured by weight are a different unit entirely.

For example:

  • 8 fluid ounces = 1 cup
  • But 8 ounces weight ≠ 1 cup

For dry ingredients like sugar and flour, recipes specify ounces by weight, not fluid ounces. Don’t confuse the two types of measurements, as that could ruin a recipe!

Fluid Ounces

Fluid ounces measure the volume or amount of space a liquid takes up. Common abbreviations used include fl oz, fl. oz, or oz.

Ounces by Weight

Ounces by weight measure the mass or heft of an ingredient. Usually the abbreviation oz. is used without a specification that it’s a “fluid” ounce.

So be aware when a recipe calls for “ounces” without “fluid” – it likely means ounces by weight, not volume. Don’t make the mistake of substituting fluid ounce measurements in those cases.

Common Conversions

Here is a summary of some handy conversions between fluid ounces, cups, and tablespoons:

  • 1 cup = 8 fluid ounces
  • 1 fluid ounce = 2 tablespoons
  • 1 cup = 16 tablespoons
  • 24 fluid ounces = 3 cups
  • 48 fluid ounces = 6 cups
  • 16 fluid ounces = 2 cups

Knowing these equivalents by heart makes converting liquid measurements a breeze. Refer back to them anytime you need to substitute amounts in a recipe.


So in summary – yes, 24 fluid ounces does equal 3 cups in volume. This handy conversion applies to any liquid ingredients. When measuring liquids for baking recipes, be sure to use proper measuring tools and techniques for maximum accuracy. And remember that fluid ounces by volume are different than ounces by weight. But for any volume measurements, you can use the equivalencies between cups, fluid ounces, and tablespoons to adjust recipe amounts as needed.
