About these units

US Fluid Ounce (fl oz)

US customaryCurrent unit

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).

Shtof (shtof)

Russian (Imperial)Historical unit (no longer in standard use)Approximate value

One tenth of a vedro, about 1.23 L. A traditional Russian bottle size for spirits.

Shtof comes from the German word Stof, which Russian used for a large goblet or flagon. The name was then given both to a squat, four-sided green glass bottle with a short neck and to the liquid measure that bottle held. Taverns known as shtof shops sold vodka and wine in sealed bottles of this size until the metric system arrived.

The size depended on the period. The standard shtof of the 19th century was one tenth of a vedro, or about 1.23 L, equal to ten charkas. An older shtof from before the 19th century held about 1.54 L, and the eight-sided shtof was one eighth of a vedro, about 1.537 L. The figure used here is the standard one tenth of a vedro, which equals 75 cubic inches.

English-language sources say little about the shtof. The English Wikipedia table of Russian measures lists the word as flagon but gives no volume, so the figures above rest mainly on the Russian Wikipedia article. In modern terms a standard shtof is a little more than a litre and a quarter, close to a large wine bottle.

1 shtof = 1.229941 liters (approximately).
