How many ounces are in 1 cup?

One cup is equivalent to 8 ounces, making this the correct response. This measurement is based on standard cooking and baking conversions, where a cup is universally recognized as containing 8 fluid ounces. Understanding this basic conversion is essential in nursing and healthcare, particularly when calculating medication dosages and fluid intake for patients. For instance, if a nurse needs to ensure a patient drinks a specific volume of fluids, knowing that 1 cup equals 8 ounces allows for accurate measurement and ensures adherence to the prescribed fluid intake.
