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).

Methuselah (methuselah)

Cooking & barCurrent unit

6 liters, eight standard bottles.

Methuselah, the oldest man in the Bible and grandfather of Noah, lends his name to a bottle of 6 liters, equal to eight standard 750 mL bottles. Wikipedia's table lists it as Imperial or Methuselah, since the same size is also called an imperial, and notes that bottle names of this kind are not applied consistently everywhere.

The naming pattern is a trade tradition rather than a rule of law. Most of the large Champagne formats borrow names of biblical kings and figures: Jeroboam, Rehoboam, Salmanazar, Balthazar and Nebuchadnezzar. The same article says the sizes section needs better sources, and in places the origins are unclear, so claims about who first used them should be treated cautiously. In practice a Methuselah is rare outside special occasions. A magnum is 1.5 L and a Methuselah four times that, about 202.9 US fluid ounces.

1 methuselah = 6 liters (exactly).
