64 fl oz is 8 cups, which is exactly half a gallon, 2 quarts or 4 pints. In metric it is about 1.89 liters.
Half-gallon cartons of milk and juice and many large water jugs hold this much. It also matches the familiar "eight 8 oz glasses" of water: 8 cups times 8 fl oz is 64 fl oz.
For measuring, two passes with a 4 cup liquid measure is quicker than eight scoops with a 1 cup. A half-gallon pitcher filled to its line works too. See ounces in a gallon and 8 cups to oz.
