About these units
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).

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).
