Ounces vs. Cups. Understanding the Measure of Things

"Cups" and "ounces" are both units of measurement commonly used in the United States and other countries that use the Imperial or U.S. customary systems.

A cup is a unit of volume equal to 8 fluid ounces (fl oz) or about 236 milliliters (ml). It is often used to measure liquids or dry ingredients such as flour or sugar when cooking or baking.

An ounce, on the other hand, is a unit of weight or mass, equal to approximately 28.35 grams (g). However, when referring to fluid ounces, it is a unit of volume, equal to about 29.57 ml. Fluid ounces are commonly used to measure the volume of liquids, such as water, milk, or juice.

The main difference between cups and ounces is that cups are used to measure volume, while ounces can be used to measure both weight and volume, depending on the context. Additionally, while cups are typically used for cooking and baking, ounces are used in a wider variety of contexts, including measuring the weight of food or drink items, such as fruits, vegetables, or coffee.
