What is the volume in milliliters of 1 cup?

The volume of 1 cup is standardized to approximately 240 milliliters. This conversion is based on the common measures used in cooking and nutrition, where 1 cup is equivalent to 8 fluid ounces. Since 1 fluid ounce is approximately 30 milliliters, multiplying 8 ounces by 30 milliliters per ounce results in a total of 240 milliliters. This conversion is widely accepted in both culinary and scientific contexts, making it a necessary measurement for various applications, especially in nursing practice where precise dosing and understanding of fluid measurements are essential.
