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).

US Quart (qt)

US customaryCurrent unit

One quarter of a US gallon, 0.946353 L (32 US fluid ounces).

Quart is a word about fractions. It comes from Latin quartus, meaning one fourth, by way of French, and it was always meant to be a quarter of a gallon. Since gallons differed over the centuries, quarts did too. The US liquid quart is 57.75 cubic inches, about 0.9464 liters, while the imperial quart is a quarter of the 4.54609-liter imperial gallon, about 1.1365 liters. Canadian French even uses pinte for the imperial quart.

Older English trade also produced odd cousins. The Winchester quart was a big bottle holding two imperial quarts, later metricated to 2.5 liters, and the reputed quart of about 0.758 liters was once a standard British wine bottle size. In the United States a quart still means a carton of milk or cream or a tub of ice cream. Americans also use a separate dry quart, about 1.101 liters, for berries, so a quart of strawberries is larger than a quart of milk.

1 US quart = 0.946352946 liters (exactly).
