About these units

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).

Metric Cup (cup)

Cooking & barCurrent unit

Exactly 250 mL. The cup used in Australia, New Zealand and most Commonwealth recipes.

A metric cup is a cup tamed by decimal thinking. Australia, Canada, New Zealand and some other former British colonies that metricated use a round 250 milliliters, exactly a quarter of a liter. Canada's older cup had been eight imperial fluid ounces, about 227.3 mL, so the metric version is noticeably larger, and Canadian recipes now usually use the 250 mL cup.

The metric cup is not an SI unit, only a practical convention, and it differs from the US cups in useful ways. It is about 6 percent larger than the US customary cup at 236.6 mL and about 4 percent larger than the 240 mL US label cup. Its arithmetic is simple: four cups make a liter, and a cup holds 50 metric teaspoons or 16 and two thirds tablespoons of 15 mL. Many recipes outside the US skip cups entirely and give dry ingredients in grams, because volume is a rough proxy for flour.

1 metric cup = 0.25 liters (exactly).
