Cup (unit) - How Many Ounces Are In A Cup

The cup is a unit of measurement for volume, used in cooking to measure liquids (fluid measurement) and bulk foods such as granulated sugar (dry measurement). It is principally used in the United States and Liberia where it is a legally defined unit of measurement. Actual cups used in a household in any country may differ from the cup size used for recipes; standard measuring cups, often calibrated in fluid measure and weights of usual dry ingredients as well as in cups, are available.

Metric cup

Some countries in the Commonwealth of Nations, notably Australia and New Zealand, define a metric cup of 250 millilitres. Units such as metric cups and metric feet are derived from the metric system but are not official metric units

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.

United States customary cup

United States customary cup is defined as half a U.S. pint.

United States "legal" cup

The cup currently used in the United States for nutrition labelling is defined in United States law as 240 ml.

Imperial cup

The imperial cup is half an imperial pint. It is no longer in common use, but many recipe books still include it.

Canadian cup

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

It should be noted that many Canadian cups follow the standard metric unit of 250 millilitres.

Japanese cup

The Japanese cup is currently defined as 200 ml.

Gō

The traditional Japanese cup, the gō, is approximately 180 ml. 10 gō make one shō, the traditional flask size, approximately 1.8 litres. Gō cups are typically used for measuring rice, and sake is typically sold by the cup (180 ml), the bottle (720 ml), and flask (1.8 litre) sizes. Note modern sake bottle sizes are almost the same as the 750 ml international standard for wine bottles, but are divisible into 4 gō.

Using volume measures to estimate mass

In Europe, cooking recipes normally state any liquid volume larger than a few tablespoons in millilitres, the scale found on most measuring cups worldwide. Non-liquid ingredients are normally weighed in grams instead, using a kitchen scale, rather than measured in cups. Most recipes in Europe use the millilitre or decilitre (1 dl = 100 ml) as a measure of volume. For example, where an American customary 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. Many European measuring cups have additional scales for common bulk ingredients like sugar, flour, or rice to make the process easier.
