What does 1 cup of macaroni equal when it is cooked?

One cup of uncooked macaroni typically yields about 2 to 2.5 cups of cooked macaroni, depending on the type of pasta and cooking method. The cooking process causes the pasta to absorb water and expand in size. Therefore, if you're measuring for a recipe, keep in mind that the cooked volume will be significantly greater than the uncooked amount.
