How to convert cubic feet to US cups
To convert cubic feet to US cups, multiply the number of cubic feet by 119.6883117. The factor is rounded to 10 significant digits. To go the other way, multiply US cups by 0.008355034722 (rounded).
US cups = cubic feet × 119.6883117
Example: 10 cubic feet = 1,196.883117 US cups.
Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.
About these units
Cubic Foot (ft³)
Exactly 28.316846592 liters (1,728 cubic inches). Used for refrigerator capacity, gas volume and shipping.
Cubic foot grew from the foot itself, a length unit with ancient origins, cubed into a volume of 1,728 cubic inches. Since the international foot was fixed at exactly 0.3048 meters, it equals exactly 28.316846592 liters. It sits at the center of the Anglo-American cubic system, a cube you could build from twelve-inch rulers, and it is about 7.48 US gallons or 6.23 imperial gallons.
In practice the cubic foot is the language of capacity and flow. Natural gas and household water are often billed per hundred cubic feet, written CCF, while gas reserves are reported in thousands and trillions of cubic feet. Rivers are measured in cubic feet per second, called cusecs, and fans and air compressors are rated in cubic feet per minute. To picture one, imagine a box a foot on each side holding a bit under seven and a half gallon jugs of water.
1 cubic foot = 28.31684659 liters (approximately).

US Cup (cup)
One sixteenth of a US gallon, 236.588 mL (8 US fluid ounces). The standard US recipe cup.
Cups began as household drinking vessels, not scientific units, which is why they remain the messiest measures in the kitchen. The US customary cup was defined by slicing up the gallon: half a pint, or eight US fluid ounces, about 236.6 milliliters. Unlike the larger units, nobody ever fixed it to a physical vessel, so it exists only as a fraction of the gallon.
The customary cup is not the only American cup. For nutrition labels, US regulation defines a cup as exactly 240 milliliters, a rounder figure that sits slightly above the customary size. Packaged foods therefore list a serving in the legal cup while a measuring cup from the hardware store follows the customary definition. The gap is 3.4 milliliters, which hardly matters for soup but can matter in baking. Cup measures also hide the weight of dry ingredients, since a cup of sifted flour and a cup of packed flour differ substantially, which is why much of the world prefers grams.
1 US cup = 0.2365882365 liters (exactly).
