What these units are
US quarts (qt). A US quart is a quarter of a US gallon, or 0.946352946 liters. It is used for milk, oil and other liquids in the United States.
Cubic feet (ft³). A cubic foot is 28.316846592 liters, and the volume of a cube one foot on each side. It is used for gas meters, freight and the capacity of appliances and containers.
US and imperial units are kept separate because they are genuinely different sizes. Confirm which system a source means before trusting a converted figure.
Converting US quarts to Cubic feet in practice
Reading the result in cubic feet
A cubic foot is the volume of a cube with edges one foot long, exactly 28.316846592 liters or 0.028316846592 cubic meters. It is a unit of volume, not of area.
Shipping containers, natural gas, water supply, refrigeration and timber are measured in cubic feet in the United States and parts of the freight trade. Appliance capacities also use it.
The cubic foot is defined through the foot, so its liter value is exact at 28.316846592. Only the displayed result is rounded, and a value taken to cubic meters and back may return with the final digit changed.
The error is confusing a cubic foot with a square foot or with a foot; volume needs three dimensions. Another is using the cubic foot where a liquid measure such as the liter or gallon is expected.
Cubic feet and cubic meters divide the same volume on different scales, and liters appear on appliance and gas labels. One cubic meter is about 35.3 cubic feet, so a figure copied between them without conversion is wrong by more than thirtyfold.
Checking a us quarts to cubic feet conversion
The metric volume units are a clean decimal chain around the liter, so liters to milliliters is a shift of three places and cubic meters to liters is a shift of three the other way. Those pairs a reader can do without a converter.
Every pair that names a US or imperial liquid unit has to go through the definition first, because three of these units differ from a metric unit by amounts too large to round away: a liter is not a quart, a gallon is 3.785411784 liters in the US system and 4.54609 in the imperial one, and a US fluid ounce is not an imperial fluid ounce.
When checking a volume conversion, convert into liters and out again, or measure the container. The mistake that survives every other check is reading a US measure as the imperial unit of the same name, which changes a recipe, a fuel figure or a tank size by about a fifth.

WaterAid puts the minimum daily water need per person at 20 litres, so one container is roughly one person's daily requirement.
