About these units

US Tablespoon (tbsp)

US customaryCurrent unit

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).

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).
