Ounce to Cup Conversion

Professor Greenline Explaining Math Concepts

We can measure volume using units like ounces, cups, pints, quarts, or gallons. Different units are used to measure different quantities. An ounce is a small unit of measurement used for smaller amounts of liquid or dry ingredients, like a tablespoon of oil or a handful of nuts. A cup is a larger unit of measurement, commonly used in cooking to measure larger quantities, like a bowl of soup or a serving of rice. Sometimes we need to change ounces to cups to make it easier to understand quantities. In this topic, we will learn how to convert ounces to cups.
