About these units
Vedro (vedro)
The Russian 'bucket', about 12.3 L (ten shtofs). The standard Russian liquid measure until metrication.
Vedro means bucket in Russian, and the unit was the main liquid measure of the Russian Empire, used for wine, vodka and other drinks. Wholesale spirits were counted in vedros and in the bochka, a barrel of 40 vedros holding about 492 L.
Peter the Great did not scrap the old Russian units but redefined them against English ones. The liquid vedro was fixed at exactly 750 cubic inches, which gives 12.29941 L, or about 2.7 imperial gallons. A separate dry vedro of 800 cubic inches, about 13.12 L, was used for grain, so the word has two values depending on the goods.
Smaller liquid units were fractions of it: a bottle of vodka was one twentieth, a kruzhka one tenth, a charka one hundredth, and the standard shtof one tenth in the 19th century. Metric units became optional in Russia in 1900, compulsory in the Russian SFSR in 1918, and the Soviet Union dropped the old measures officially in 1925.
1 vedro = 12.29941 liters (approximately).

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).
