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).

Jeroboam (jeroboam)

Cooking & barCurrent unitApproximate value

3 liters, four standard bottles, in Champagne and Burgundy. In Bordeaux a jeroboam is 4.5 liters.

Large wine bottles carry the names of Old Testament kings, and Jeroboam, the first ruler of the northern kingdom of Israel, was given to a bottle that holds four standard 750 mL bottles. In Champagne and Burgundy it holds 3 litres, the figure used here, and it is equal to a double magnum. Wikipedia's article on wine bottles lists a second value of 4.5 litres, or six standard bottles, for the Bordeaux usage, so the name does not always mean the same volume.

That second meaning makes a Bordeaux jeroboam the same size as a rehoboam, which is the name used for 4.5 litres elsewhere. Neighbouring sizes run from the magnum at 1.5 litres to the methuselah at 6 litres, then the salmanazar at 9 litres. Sizes beyond the jeroboam are rare. The Wikipedia article on Champagne bottles confirms the 3 litre size and notes that these names are mostly drawn from biblical figures. Anyone converting should check which region's bottle is meant.

1 jeroboam = 3 liters (approximately).
