Fluid ounces vs weight ounces
A quart is a volume, so it is measured in fluid ounces. A quart of water happens to weigh about 33.4 ounces, but a quart of flour weighs only about 17.6 ounces, so never swap the two for dry ingredients.
Quart containers you will see
Deli containers, yogurt tubs and broth cartons often come in 32-ounce (1-quart) sizes, and a pint container of ice cream is half of that at 16 ounces. A 64-ounce bottle of juice is 2 quarts, and a gallon jug is 4 quarts, or 128 ounces. If a recipe calls for a quart of stock and you have 14.5-ounce cans, you need a little more than two cans.
