About Quart (qt)
A US customary unit of volume equal to 2 pints, 4 cups, or 1/4 of a gallon (about 946 mL). Quarts are the common US retail size for milk, juice, motor oil, and paint cans. A quart is almost exactly equal to one liter (~5% less), which is why many international product containers labeled in liters serve the same role as US quart sizes without needing a separate SKU. The Imperial quart (UK) is larger at 1.136 liters.
About Gallon (US) (gal)
A US customary unit of volume equal to exactly 3.785411784 liters, or 128 fluid ounces. US gallons are the default unit for US gasoline pricing and fuel economy (miles per gallon), milk and beverage containers, water heaters, and pool/aquarium capacity. Different from the Imperial gallon used in the UK (4.546 L) — a frequent source of confusion when comparing US vs. UK fuel economy or trans-Atlantic recipes. One US gallon weighs about 8.34 pounds.
