Break it down with me: 1 cup = 8 fluid ounces. So 2 cups = 16 ounces. Add in that half-cup (4 ounces), and you get 20 ounces. See? Your third-grade teacher would be so proud. Even if you were doodling in the margins back then.
But what if you need half of 2 1/2 cups? That’s 1 1/4 cups, which is 10 ounces. Math is basically a party trick at this point. “Hey, guess how many ounces in 2 1/2 cups?” You’ll be the star of every kitchen conversation—until they ask about grams, and then you just smile and change the subject.
Why Does This Even Matter?
Because recipes are picky, and burnt cookies are sad. Getting the right measurement is the difference between a soufflé that rises like a champ and one that looks like a deflated balloon. Precision is your best friend—even if you usually wing it like me. A little structure keeps the kitchen chaos under control.

Plus, knowing this little fact means you can convert recipes in your head. Say a recipe calls for 2 1/2 cups of broth, but you only have a 16-ounce container left. You’ll know you need to add 4 more ounces—or just grab another container. Easy peasy, lemon squeezy.
