About these units

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).

Hogshead (ale) (hhd (ale))

Imperial (British)Historical unit (no longer in standard use)

54 imperial gallons (245.5 L), one and a half UK beer barrels.

Philologists such as Walter William Skeat traced hogshead to Germanic words for a cask, for example Dutch oxhooft and Danish oxehoved, meaning ox head; the older English form was probably oxhead. Parliament first tried to standardise the cask in an act of 1423, but sizes still varied by place and by what was inside.

For ale, Wikipedia gives two figures. Under the pre-1824 beer gallon the ale hogshead is listed as 45 imperial gallons, while its chart for the 1824 system gives 54 imperial gallons, 245.5 liters, one and a half barrels. The latter is the figure used here. Other goods differed: wine hogsheads settled at 52.5 imperial gallons (238.7 L), and in 1897 Whitaker's Almanack listed 46 gallons for claret, 57 for port and 54 for sherry. Colonial sugar and tobacco hogsheads were measured by weight instead. The ale hogshead has long fallen out of use.

1 hogshead (ale) = 245.48886 liters (exactly).
