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 Fluid Ounce (fl oz)
One 128th of a US gallon, 29.5735 mL. Not the same as the weight ounce, and about 4% larger than the imperial fluid ounce.
Fluid ounce began as an attempt to link volume to weight: the volume occupied by one ounce of some substance, such as wine in England or water in Scotland. Definitions varied by region and by liquid. When Britain defined its imperial gallon in 1824 as the space of ten pounds of water, the imperial fluid ounce came out so that an ounce of water weighs about one avoirdupois ounce. The US fluid ounce followed a different path and comes from the older wine gallon.
The US fluid ounce is exactly 1/128 of a US gallon, 29.5735295625 milliliters, about 4 percent bigger than the imperial one at 28.4130625 milliliters. American nutrition labels use yet another figure, treating one fluid ounce as 30 milliliters, a convenient rounding for serving sizes. The name is a trap, because a fluid ounce measures space while a weight ounce measures mass. A US fluid ounce of water weighs a bit more than an ounce of weight, while a fluid ounce of honey weighs considerably more.
1 US fluid ounce = 0.02957352956 liters (approximately).
