The cup is a United States unit of volume, most commonly associated with cooking and serving sizes. It is traditionally equal to half a liquid pint in US customary units but is now separately defined in terms of the metric system at values between 1/5 and 1/4 of a liter. Because actual drinking cups may differ greatly from the size of this unit, standard measuring cups are usually used instead.

United States
Legal cup
The cup currently used in the United States for nutrition labelling is defined in United States law as 240 mL.
Customary cup
In the United States, the customary cup is half of a liquid pint.
A customary "cup" of coffee in the U.S. is usually defined as 4 fluid ounces, brewed using 5 fluid ounces of water. Coffee carafes used with drip coffee makers, such as Black and Decker models, have markings for both water and brewed coffee, since the carafe is also used for measuring water prior to brewing. A 12-cup carafe, for example, has markings for 4, 6, 8, 10, and 12 cups of water or coffee, which correspond to 20, 30, 40, 50, and 60 fluid ounces of water or 16, 24, 32, 40, and 48 fluid ounces of brewed coffee, respectively, the difference being the volume lost to evaporation during brewing.

Commonwealth of Nations
Metric cup
Australia, Canada, New Zealand, and some other members of the Commonwealth of Nations--being former British colonies that have since metricated--employ a "metric cup" of 250 millilitres. Although derived from the metric system, it is not an SI unit.
A "coffee cup" is 1.5 dL or 150 millilitres or 5.07 US customary fluid ounces, and is occasionally used in recipes. It is also used in the US to specify coffeemaker sizes (what can be referred to as a Tasse à café). A "12-cup" US coffeemaker makes 57.6 US customary fluid ounces of coffee, or 6.8 metric cups of coffee. In older recipes cup may mean "coffee cup".
Canadian cup
Canada now usually employs the metric cup of 250 mL but its conventional cup was somewhat smaller than both American and imperial units.
1 Canadian cup = 8 imperial fluid ounce = 1/20 imperial gallon = 227.3045 millilitres
1 tablespoon = 1/2 imperial fluid ounce
1 teaspoon = 1/6 imperial fluid ounce
International
Similar units in other languages and cultures are sometimes translated "cup", usually with various values around 1/5 to 1/4 of a liter.
Latin American cup
In Latin America, the amount of a "cup" (Spanish: taza or vaso) varies from country to country, with some intending 200 mL, others 250 mL, and still others the US legal or customary amount.
Japanese cup
The traditional Japanese unit equated with a "cup" size is the g?, legally equated with 2401/13310 liters (?180.4 mL) in 1891. It is still used for reckoning amounts of rice and sake. Separately, the Japanese standardized a "cup" defined as 200 mL.
Dry measure
In Europe, recipes normally weigh non-liquid ingredients in grams rather than measuring volume. For example, where an American recipe might specify "1 cup of sugar and 2 cups of milk", a European recipe might specify "200 g sugar and 500 ml of milk" (or 0.5 litre or 5 decilitres). Conversion between the two measures must take into account the density of the ingredients, and some recipes specify both weight and volume to simplify. Many European measuring cups have markings that indicate the weight of common ingredients for the a given volume.
