One quart (qt) is equal to 32 fluid ounces (oz) in the United States customary system. This applies specifically to liquid measurements, where 1 quart = 32 fluid ounces

. There is a distinction between liquid and dry quarts:

• A liquid quart contains 32 fluid ounces.
• A dry quart weighs approximately 37 ounces, but this is a measure of weight, not volume

For practical purposes, especially in cooking and liquid volume measurement, use the conversion: 1 quart = 32 fluid ounces.
