About these units
US Cup (cup)
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 Barrel (bbl (dry))
Exactly 7,056 cubic inches (115.628 L). The US standard barrel for dry goods such as fruit and vegetables.
A barrel for dry goods is the only cask in this family defined by a clean cubic measure rather than by gallons. The US standard is 7,056 cubic inches, which converts to about 115.6 litres (115.63 L as used here) and equals roughly 3.3 US bushels. Unlike the many English cask names built on the wine gallon, this barrel descends from the corn measure used for grain, fruit and root crops.
The word barrel entered English in the Middle Ages from French baril, a term whose own origin is unknown. In American commerce the dry version served for flour, cornmeal, sugar, lime, cement, salt and produce such as apples, though cornmeal, for instance, is reckoned by weight at 200 pounds per barrel.
The fixed cubic-inch definition keeps the unit stable, and it is regularly confused with the liquid barrel of 31.5 gallons, which is a little larger at about 119 litres. Modern trade has largely replaced both with sacks, cartons and metric weights, though the dry barrel remains defined in US customary tables.
1 US dry barrel = 115.6271236 liters (approximately).
