About these units
Charka (charka)
One hundredth of a vedro, about 123 mL. The traditional Russian shot of vodka.
Charka is a Russian word for a small drinking cup, and the Russian Wikipedia article says the word reached Russian from Turkish. Ornate silver and enamelled charkas for strong spirits were part of everyday Russian life in the 17th and 18th centuries, and the oldest example in the Kremlin Armory dates from 1515.
As a measure, the charka was one hundredth of a vedro, or 7.5 cubic inches, which comes to about 123 mL. It sat in a chain of small liquor measures: half a charka was a shkalik of about 61.5 mL, two charkas made a chetushka of about 246 mL, and ten made a kruzhka of about 1.23 L. The English Wikipedia table of Russian units uses these same fractions of the vedro.
Russia fixed these measures relative to English cubic inches under Peter the Great, so the charka is a precise figure on paper even if real cups varied. The metric system replaced it in the 1920s, yet the word survives as the normal Russian name for a shot glass, and a charka is still close to a double shot today.
1 charka = 0.1229941 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).
