About these units
US Dry Quart (dry qt)
One 32nd of a US bushel (1.1012 L), about 16% larger than a liquid quart. Used for berries and small produce.
Quart comes from the Latin quartus, a fourth, by way of French, and a quart is meant to be a quarter of a gallon. American usage splits the unit in two, though, because a liquid gallon and a dry gallon were never the same. The dry quart is 1/32 of a US bushel, 67.200625 cubic inches, about 1.101 L. The liquid quart is 57.75 cubic inches, about 0.946 L, so the dry one is roughly 16 percent larger.
Britain avoids this split, since the imperial system has one quart for both liquids and solids, 69.35 cubic inches or about 1.1365 L, and it is a little larger than the American dry quart. Because gallons of many sizes were once in use, quarts have also come in many sizes, and the dry quart itself sometimes varied by commodity. Berries and small produce are the usual goods sold by it. NIST lists it as 1.101221 L.
1 US dry quart = 1.101220943 liters (approximately).

US Gallon (gal)
Exactly 231 cubic inches or 3.785411784 liters (128 US fluid ounces). About 17% smaller than the imperial gallon.
The US gallon is a survivor of English wine trade. Around 1706, a statute in Queen Anne's reign fixed the wine gallon at exactly 231 cubic inches, settling confusion among the competing gallons for wine, ale and corn. British colonies in North America used that wine gallon, and in 1824 Britain replaced all its gallons with a new imperial one while the United States kept the old measure. It was adopted as the legal US standard in 1836 and is still defined as exactly 231 cubic inches, or 3.785411784 liters.
That makes the US gallon about 17 percent smaller than the imperial gallon, a difference that explains why American and British fuel-economy figures cannot be compared directly. Everyday uses are milk jugs, paint cans and gasoline pumps. One gallon divides evenly into four quarts, eight pints, sixteen cups and 128 fluid ounces. A gallon of water weighs a little over 8 pounds, an easy figure to remember when loading a car with water jugs.
1 US gallon = 3.785411784 liters (exactly).
