About these units
UK Beer Barrel (bbl (UK))
36 imperial gallons (163.66 L). A traditional British beer barrel.
Barrel entered English from medieval French baril, a word of unknown origin. Across medieval Europe barrels ranged from roughly 100 to 1,000 liters depending on place and contents, so the brewer's barrel is only one of many. In British brewing it is fixed at 36 imperial gallons, about 164 liters (163.66 L at the figure used here) or roughly 43 US gallons.
The size matters because the other traditional beer casks are fractions of it. A firkin is a quarter of a barrel at 9 gallons, a kilderkin is half at 18 gallons, and the barrel itself is two kilderkins or four firkins. Today the barrel survives mainly as an accounting unit in brewery statistics rather than as a physical container, since most beer now travels in metal kegs measured in liters.
1 UK beer barrel = 163.65924 liters (exactly).

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).
