Coffee cup

A "cup" of coffee in the US is usually 4 fluid ounces (118 ml), brewed using 5 fluid ounces (148 ml) of water. Coffee carafes used with drip coffee makers, e.g. Black and Decker models, have markings for both water and brewed coffee as 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 US fluid ounces (0.59, 0.89, 1.18, 1.48, and 1.77 litres) of water or 16, 24, 32, 40, and 48 US fluid ounces (0.47, 0.71, 0.95, 1.18, and 1.42 litres) of brewed coffee respectively, the difference being the volume absorbed by the coffee grounds and lost to evaporation during brewing.

Canadian cup

Canada now usually employs the metric cup of 250ml, but its conventional cup was somewhat smaller than both American and imperial units. 1 Canadian cup = 8 imperial fluid ounces = imperial gallon = 1 tablespoon = 1 teaspoon =

Similar units in other languages and cultures are sometimes translated "cup", usually with various values around to of a litre.


Latin American cup

In Latin America, the amount of a "cup" ( es, link=no, taza) varies from country to country, using a cup of 200ml, 250ml, and the US legal or customary amount.

Russian cup

The traditional Russian measurement system included two cup sizes, one of which, the "charka" (cup proper), was usually used for alcoholic drinks and measured , while another, "stakan" ("glass") was twice as big at and used for other liquids. Since metrication, the charka was informally redefined as 100 ml, acquiring a new name of "stopka" (related to the traditional Russian measurement unit "stopa" :ru:%D0%A1%D1%82%D0%BE%D0%BF%D0%BA%D0%B0), while there are currently two widely used glass sizes of 250 and 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". A precise conversion between the two measures takes into account the density of the ingredients, and some recipes specify both weight and volume to facilitate this conversion. Many European measuring cups have markings that indicate the weight of common ingredients for a given volume.
