A simple plastic measuring cup for liquids
The cup is a unit of measurement for volume, used in cooking to measure bulk foods, such as granulated sugar (dry measurement), and liquids (fluid measurement). Sugar is a class of edible Crystalline substances mainly Sucrose, Lactose, and Fructose.

The British Empire was the largest empire in history and for over a century was the foremost global power. The United States of America —commonly referred to as the For a topic outline on this subject see List of basic Japan topics. This cup is not commonly used in the United Kingdom or the rest of Europe, however an informal cup referring to the volume of an average coffee cup (and thus noticeably different than the U. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located S. cup) is frequently used in recipes in other countries such as Germany.
There is no internationally agreed standard definition of the cup, which ranges in volume between 200 and 250 millilitres. The litre or liter (see spelling differences) is a unit of Volume.  Because the cup sizes generally used in the many Commonwealth countries and the United States differ only by about 13 ml (0. 5 fl oz), the respective measures are close enough for cooking. A fluid ounce (abbreviated fl oz, fl oz or oz fl) is a unit of Volume in both the imperial and the US customary systems

- Imperial cup
- The imperial cup was defined as half an imperial pint. The pint is an English unit of Volume or capacity in the imperial system and United States customary units. The unit is no longer in use.

Using volume measures to estimate mass
In metric regions, cooking recipes normally state any liquid volumes larger than a few tablespoons in millilitres, the scale found on most measuring cups worldwide. A measuring cup is a kitchen utensil used primarily to measure the Volume of liquid or powder-form Cooking ingredients such as water milk juice flour Non-liquid ingredients are normally weighed in grams instead, using a kitchen scale, rather than measured in cups. Some recipes in Europe use the decilitre (1 dl = 100 ml) as a cup-like measure. For example, where an American customary recipe might specify "1 cup of sugar and 2 cups of milk", a metric recipe might specify "200 g sugar and 500 ml of milk" (or ½ litre or 5 decilitres). Conversion between the two measures must take into account the density of the ingredients.

- ^ Note also that cup sizes in recipes do not necessarily equate serving sizes for beverages. For example, a cup of brewed coffee in the U. CoFFEE is an Open source Software for computer supported collaborative learning (CSCL in a digital classroom S. is traditionally only 6 U. S. fluid ounces (180 ml).

Note that the kilogram was originally defined as the mass of one litre of water and, similarly, the imperial gallon was originally defined as the volume occupied by ten avoirdupois pounds of water. The slight discrepancy is due to the fact that water of different temperatures was used—about 4 °C (39 °F) for the kilogram definition and 62 °F (17 °C) for the imperial gallon. The U. S. fluid ounce is slightly larger.
- 1 g/ml ≈ 1. 002 av oz/imp fl oz
- 1 g/ml ≈ 1. 043 av oz/U. S. fl oz
- ^ 1 g/ml is a good rough guide for other water-based liquids such as milk (the density of milk is about 1. 03–1. 04 g/ml).
- ^ The density of water ranges from about 0. 96 to 1. 00 g/ml dependant on temperature and pressure. The table above assumes a temperature range 0–30°C (32–86°F). This variation is not generally a concern when cooking.
- ^ Since an imperial cup of water weighs approximately 10 avoirdupois ounces and five imperial cups are approximately equal to six U. S. cups, one U. S. cup of water weighs approximately 8⅓ avoirdupois ounces.
