About these units

Cubic Foot (ft³)

US & ImperialCurrent unit

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).

Metric Tablespoon (tbsp)

Cooking & barCurrent unit

Exactly 15 mL, used in most countries.

Fifteen milliliters is the working size of the tablespoon in most of the world, and it is a rounded figure. Older customary values were about 14.8 mL for the US and about 14.2 mL for the UK, and modern UK and US measuring spoons are both treated as 15 mL in most contexts. The tablespoon itself dates to the early 1700s, when it first appeared in place settings for soup.

The 15 mL spoon is a staple in recipes everywhere. Three metric teaspoons make a tablespoon, and 16 and two thirds make a 250 mL metric cup. Australia is the notable exception, using a 20 milliliter tablespoon and counting four teaspoons to it, so a recipe from one country can taste off in another. Check which spoon a cook has in mind: scoops of oil, honey or baking powder amount to a third more in Australia.

1 metric tablespoon = 0.015 liters (exactly).
