Cup (unit)

There is, however, no internationally agreed upon standard definition of the cup, largely because different nations have diverged in the laws which defined the more basic Unit , the Fluid Ounce . Consequently, its volume ranges between 1/5 (0.20) and 1/4 (0.25) Litre (200 — 250 ML ) in the Metric System , the international standard Measurement System . The difference in the legal Ounce is relatively insignificant for household purposes as the ratiometric difference in volume is only ^1.73(U.K.)⁄_1.81(USA) (about 96%).

Recipes in cookbooks will naturally use their local Customary Units , but since the cups used in the Commonwealth Of Nations and the United States differ by only ¹⁄₂ (0.5) Fl Oz , the respective measures are close enough for cooking purposes.

) is 180 ml; 10 Japanese cups together make one Shou , the traditional flask size, of 1.8 liter. Sake is typically sold by both the cup (180 ml) and flask (1.8 liter) sizes.

Cup sizes implied in cooking recipes do not necessarily define serving sizes for beverages. For example, a cup of brewed Coffee in the U.S. is traditionally 6 U.S. Fluid Ounce s (180 mL) instead.
