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).

Butt (pipe) (butt)
126 US gallons (477 L), also called a pipe: half a tun.
Butt is an obsolete English liquid measure equal to two hogsheads, and for wine it is also called a pipe. At 126 US wine gallons, or 105 imperial gallons, it holds about 477 litres (476.96 L as used here). It is half a tun, so two butts fill the largest standard cask.
The size was never fully fixed. Depending on the definition a butt ranged from about 450 to 1,060 litres, and an ale butt of roughly 108 imperial gallons (about 491 litres) differed from the wine butt. The Oxford English Dictionary is cited as warning that these standards were not always followed precisely.
The informal word buttload, meaning a large quantity, is one proposed descendant of the measure. A 1695 gauging manual by James Lightbody lists beer and ale vessels by name and content.
1 butt (pipe) = 476.9618848 liters (approximately).
