About these units
US Quart (qt)
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).

US Teaspoon (tsp)
One sixth of a US fluid ounce, exactly 4.92892159375 mL. Commonly rounded to 5 mL in recipes.
Teaspoons arrived with tea. Small spoons were common in Europe from at least the 13th century, and the earliest cited mention of a teaspoon is a London Gazette advertisement from 27 December 1686. Britain's Commutation Act of 1784 cut the tea tax from 119 percent to 12.5 percent, tea became cheap, and cups and spoons grew with it. By the 1850s the culinary teaspoon had settled as one third of a tablespoon.
The US teaspoon is one sixth of a US fluid ounce, exactly 4.92892159375 milliliters, though for nutrition labels and medicine it is rounded to 5 mL. Apothecaries once called the small spoon cochleare minus, to distinguish it from the larger cochleare majus. Household spoons are poor measuring tools: one study of 71 kitchen teaspoons found volumes from 2.5 to 7.3 milliliters, which is why dosing instructions point to standard measuring spoons or syringes.
1 US teaspoon = 0.004928921594 liters (approximately).
