The Imperial pint is equivalent to approximately 568 mL while the US customary pint is considered equivalent to around 473 mL. However, due to the fact that the US unit system and the Imperial system have different volume definitions, the American pint is actually about 20% smaller than the British Imperial pint. The pint is traditionally considered equivalent to 1/8th of a gallon in both the United States customary units system and the Imperial measurement system. Since the revision of the metric system, the cup proper was redefined as being equivalent to 100 mL while the glass measurement sizes are 200 mL and 250 mL respectively. Meanwhile, the “cup proper” was used to measure out alcoholic liquids and is equivalent to 123 mL. Russia has additional cup sizes, including the “glass” measurement which is equivalent to approximately 246 mL, used to measure nonalcoholic liquids. The regular Japanese standardized cup has a definition of being equal to 200 mL. While the unit of measurement is rarely used by modern Japan, it is occasionally used to measure out amounts of sake and rice. Japan has a unit of measurement, called the gō, very similar in size to the cup, being approximately 180 mL. While these aren’t exactly equivalent to metric cups, they bear mentioning. Other nations like Japan, Russia and various nations across Latin America have their own measurements that translate roughly to “cup” and typically have a similar volume around 1/5th to 1/4th or a liter.


This proved to be rarely used, and the metric cup is used instead of when ingredients can be measured by weight and require a volume measurement. The standardized cup in the United Kingdom was at one time set at half an Imperial pint or 10 Imperial fluid ounces. A traditional Canadian cup was equal to eight Imperial fluid ounces or 227 mL. Canada had its own definition of cup, though it now mainly uses the metric cup that is 250 mL. Under this system of measurement, 1 cup is equivalent to 250 mL, a value that is about 5.07 customary fluid ounces in the United States. The “metric cup” is used by New Zealand, Canada, and Australia as a well as some other Commonwealth nations. These nations have a system of measurement that is similar to the system of measurement used by the international system of units but isn’t exactly equivalent. Great Britain, Canada, Australia, India, and various nations across Africa are member states of the Commonwealth of Nations. The Commonwealth of Nations is a political association including over 50 different member states, most of which belonged to the British Empire at some point or another. Cups are also equal to 8 fluid ounces or 16 tablespoons. Meanwhile, the customary definition of a cup is that it is one half of a US customary pint, one-fourth of a quart, and 1/16 of a gallon. Note that there is a difference between ounces in US customary units and US Imperial units, and for this reason, cups are equivalent to about 8.45 Imperial fluid ounces, slightly more than the US amount. In the United States customary system, one cup is defined by the United States law as being equal to 240 mL, or approximately 8.12 customary fluid ounces. A cup has a definition in a legal sense and in the customary or regular sense. The United States has two different methods of defining the volume of the cup. Let’s go over some of the different ways cups are quantified. The common or traditional definition of a cup is half a liquid pint when measuring in the United States customary units, yet the cup is also defined in the metric system with a value somewhere between 1/5th and one-fourth of a liter.ĭifferent nations and different measurement systems have their own exact specifications for the volume of the cup. The most common use for measuring in cups is when determining serving sizes and/or when cooking. The Cup Unit Of MeasurementĬups are a unit of measurement, specifically a unit of volume of measurement. Let’s take a look at how both cups and pints are measured, and understand the different definitions that might be used when determining how many cups fit into a pint. While this seems like a simple answer, there are actually different ways of measuring cups and pints, and for this reason, the answer to this question is more complicated than it may initially appear. Exactly how many cups are in a pint? There are 2 cups in one pint, when measured in the United States customary units.
