Question: how many fluid ounces in a cup of coffee?
Answer: A "cup" of coffee in the US is usually 4 fluid ounces (118 mL), brewed using 5 fluid ounces (148 mL) of water. Coffee carafes used with drip coffee makers, e.g. Black and Decker models, have markings for both water and brewed coffee as the carafe is also used for measuring water prior to brewing.
