That is the question that has been on many people’s minds for the past few weeks. On one side of the debate is those who believe that 1/3 of a cup is equal to 3 ounces, while on the other side are those who believe that 1/3 of a cup is equal to 1 ounce. There are a few reasons why this question has come up. One reason is because there are 3 teaspoons in a tablespoon, and because 1/3 of a cup is equal to 3 teaspoons, it would make sense that it would be equal to 1 ounce as well. Additionally, when measuring ingredients like flour or sugar, it can be helpful to divide them into thirds or even quarters so that you have more accurate measurements.
