About these units

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).

US Cup (cup)

US customaryCurrent unit

One sixteenth of a US gallon, 236.588 mL (8 US fluid ounces). The standard US recipe cup.

Cups began as household drinking vessels, not scientific units, which is why they remain the messiest measures in the kitchen. The US customary cup was defined by slicing up the gallon: half a pint, or eight US fluid ounces, about 236.6 milliliters. Unlike the larger units, nobody ever fixed it to a physical vessel, so it exists only as a fraction of the gallon.

The customary cup is not the only American cup. For nutrition labels, US regulation defines a cup as exactly 240 milliliters, a rounder figure that sits slightly above the customary size. Packaged foods therefore list a serving in the legal cup while a measuring cup from the hardware store follows the customary definition. The gap is 3.4 milliliters, which hardly matters for soup but can matter in baking. Cup measures also hide the weight of dry ingredients, since a cup of sifted flour and a cup of packed flour differ substantially, which is why much of the world prefers grams.

1 US cup = 0.2365882365 liters (exactly).
