About these units

US Cup (cup)

US customaryCurrent unit

One sixteenth of a US gallon, 236.588 mL (8 US fluid ounces). The standard US recipe cup.

Cups began as household drinking vessels, not scientific units, which is why they remain the messiest measures in the kitchen. The US customary cup was defined by slicing up the gallon: half a pint, or eight US fluid ounces, about 236.6 milliliters. Unlike the larger units, nobody ever fixed it to a physical vessel, so it exists only as a fraction of the gallon.

The customary cup is not the only American cup. For nutrition labels, US regulation defines a cup as exactly 240 milliliters, a rounder figure that sits slightly above the customary size. Packaged foods therefore list a serving in the legal cup while a measuring cup from the hardware store follows the customary definition. The gap is 3.4 milliliters, which hardly matters for soup but can matter in baking. Cup measures also hide the weight of dry ingredients, since a cup of sifted flour and a cup of packed flour differ substantially, which is why much of the world prefers grams.

1 US cup = 0.2365882365 liters (exactly).

US Dry Quart (dry qt)

US customaryTraditional unit (still used in some regions)

One 32nd of a US bushel (1.1012 L), about 16% larger than a liquid quart. Used for berries and small produce.

Quart comes from the Latin quartus, a fourth, by way of French, and a quart is meant to be a quarter of a gallon. American usage splits the unit in two, though, because a liquid gallon and a dry gallon were never the same. The dry quart is 1/32 of a US bushel, 67.200625 cubic inches, about 1.101 L. The liquid quart is 57.75 cubic inches, about 0.946 L, so the dry one is roughly 16 percent larger.

Britain avoids this split, since the imperial system has one quart for both liquids and solids, 69.35 cubic inches or about 1.1365 L, and it is a little larger than the American dry quart. Because gallons of many sizes were once in use, quarts have also come in many sizes, and the dry quart itself sometimes varied by commodity. Berries and small produce are the usual goods sold by it. NIST lists it as 1.101221 L.

1 US dry quart = 1.101220943 liters (approximately).
