Yes, 8 ounces (oz) is equivalent to 1 cup (c) in terms of liquid volume measurement. This conversion applies specifically to liquid ingredients and is commonly used in cooking and baking recipes.

In the United States, the customary system of measurement is commonly used for cooking and baking, which includes cups and fluid ounces as units of volume. In this system, 1 cup is equal to 8 fluid ounces. Therefore, if a recipe calls for 1 cup of milk, you can use a measuring cup to measure out 8 fluid ounces of milk instead.
It’s important to note, however, that this conversion only applies to liquid ingredients. When measuring dry ingredients, the weight-to-volume ratio may be different depending on the ingredient. For example, 1 cup of all-purpose flour weighs approximately 4.5 ounces, while 1 cup of granulated sugar weighs approximately 7 ounces.
In addition, it’s also important to use the appropriate measuring tools when measuring ingredients. A standard measuring cup should be used for measuring liquid ingredients, while dry ingredients should be measured using a dry measuring cup or a kitchen scale.
Overall, when measuring liquid ingredients in cooking and baking, 8 ounces is equivalent to 1 cup. By following standard measurement practices and using the appropriate measuring tools, you can ensure that your recipes turn out as intended.
