US Tablespoons to Cubic Feet (tbsp to ft³)
1 US tablespoon equals 0.0005221896701 cubic feet (rounded).
How to convert US tablespoons to cubic feet
To convert US tablespoons to cubic feet, multiply the number of US tablespoons by 0.0005221896701. The factor is rounded to 10 significant digits. To go the other way, multiply cubic feet by 1,915.012987 (rounded).
cubic feet = US tablespoons × 0.0005221896701
Example: 10 US tablespoons = 0.005221896701 cubic feet.
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
US Tablespoon (tbsp)
Half a US fluid ounce (14.787 mL), equal to 3 teaspoons.
A tablespoon was once a spoon first and a unit second. Tablespoons entered place settings around 1700, first reserved for soup, and in the 18th century apothecaries used an unofficial tablespoon of four fluid drams, or half a fluid ounce. That is the origin of the modern US definition, which turns the spoon into precisely half a US fluid ounce.
The US tablespoon is therefore 14.7868 milliliters, equal to three US teaspoons, and sixteen of them make a US customary cup. It is often treated as 15 mL, and American nutrition labels define a tablespoon as exactly 15 mL, so the two figures sit within about 1.4 percent of each other. The regional difference that matters is Australia, which uses a larger 20 milliliter tablespoon, so a recipe asking for a tablespoon of oil or baking powder can go wrong when translated across the Pacific.
1 US tablespoon = 0.01478676478 liters (approximately).

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).
