About Cup (cup)
A US customary unit of volume equal to 8 fluid ounces or about 237 milliliters. Cups are the dominant measurement unit in American home cooking and published US recipes — a standard measuring cup set includes 1, 1/2, 1/3, and 1/4 cup scoops. Outside North America, recipes typically use grams (for solids) and milliliters (for liquids), making cup→ml conversions one of the most common kitchen conversions for international cooks working from American cookbooks.
About Fluid Ounce (fl oz)
A US customary unit of liquid volume equal to 1/128 of a US gallon (about 29.57 mL). Fluid ounces are the standard unit on US beverage containers, shampoo bottles, cooking recipes, and cocktail recipes — a standard US soda can is 12 fl oz, a large Starbucks drink is 20 fl oz, and most cocktails call for 1.5 fl oz of spirits. Easy to confuse with the Imperial fluid ounce (~28.41 mL) used in the UK, though the difference is small enough that it rarely matters for everyday use.
