About these units
US Cup (cup)
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).

Imperial Gill (gi (UK))
Five imperial fluid ounces, 142.07 mL, a quarter of an imperial pint. Formerly a UK spirits measure.
Gill, pronounced with a soft g, is the quarter pint of the imperial system: five imperial fluid ounces, or 142.0653125 milliliters, which is about 4.8 US fluid ounces. Four gills make a pint, eight make a quart and thirty-two make a gallon. The unit is also known as a teacup, and half a gill is sometimes called a jack.
Its best-known use was in selling spirits. Before metrication, English pubs poured spirits in sixths of a gill (about 23.7 mL), Scottish bars in fifths (28.4 mL) or quarters (35.5 mL), and Northern Ireland and the Republic of Ireland used the quarter gill. Scottish drinkers also had names such as the nip for a quarter gill and the wee gill for three quarters of a gill. After UK metrication, pubs moved to 25 mL or 35 mL measures, while the Isle of Man kept the one-fifth gill until 2022. Outside the drinks trade the gill is now rare and mostly appears in old recipes and statutes.
1 imperial gill = 0.1420653125 liters (exactly).
