The Simple Answer: Fluid Ounces in a Quarter Cup

A quarter cup equals 4 fluid ounces (fl oz).

This count applies specifically to fluid quarter cups—the standard measurement used in most U.S. recipe systems.

What Is a Quarter Cup? Understanding the Unit

A quarter cup is a standard dry or liquid measurement used primarily in U.S. cooking and baking. It’s part of the U.S. customary system, where ingredients are measured in cups, fluid ounces, teaspoons, tablespoons, etc.

While some international recipes use metric cups (where 1 cup = 240 mL), the U.S. quarter cup is strictly 4 fluid ounces—a crucial detail for accurate substitutions and scaling.
