A cup is a standardized unit of volume. The capacity of a cup can vary from one country to another, but it usually ranges from about 0.1 l (10 dm³) to 2 L (200 dm³). The exact size of any cup depends on its use and the type of liquid it contains. For example, cups for drinking tea are usually larger than those for drinking coffee.
Cups are used in cooking and baking to measure liquids such as water, milk or cream. They can also be used for measuring dry ingredients like flour and sugar, but this is not common in the United States outside of bakeries where recipes are often written using metric measurements. In the U.S., most recipes are measured by volume rather than weight, so you need to know how many cups make up 1 pound (0.45 kg).
