You may use the cups to ounces converter above to convert cups to ounces (oz). You can also use the cups to the ounces table to figure out how many ounces are in “Y” cups. Below you’ll find instructions on how to calculate the number of ounces in “Y” cups, with formulas and examples of conversions. The conversion table and converter are based on US cups and fluid ounces.
Cups come in a variety of sizes, including the US cup, Metric cup, Imperial cup, and Canadian cup. The US fluid ounce and the Imperial fluid ounce are the two varieties of fluid ounces. As a result, the answer to the question of how many fluid ounces are in a cup may vary depending on which types of cups and fluid ounces are used. There are 8 fluid ounces in a cup when converting from US cups to fluid ounces.
Cups
A cup is a volume measuring unit used in cooking to measure bulk items such as chopped vegetables (a dry measurement example) or liquids such as milk (fluid measurement). It is widely used in many countries, particularly those that were once part of the British Empire, such as the United States and most Commonwealth of Nations members, as well as those that aspired to be like them, such as Japan.
A cup is a volume measurement that equals 16 tablespoons or 8 fluid ounces. The cup is not to be confused with the metric cup or the teacup, which are both separate volume units. Although one cup is almost about 236.6 millilitres, it is labelled as 240 millilitres on nutrition labels.
The cup is a standard volume measurement in the United States. Cups are commonly shortened as C and can alternatively be abbreviated as c. 1 cup, for instance, can be written as 1 c or 1 C.
Fluid Ounces
A fluid ounce is a volume unit that is used in both the Imperial and US customary units systems. The two metrics, however, are not identical: The imperial fluid ounce is around 1.734 cubic inches or 28.4130625 millilitres, or 1/160 of an imperial gallon, 1/20 of an imperial pint, or 8 fluid drams. This volume of water weighs about 1 avoirdupois ounce (the volume occupied by one ounce at 62 degrees Fahrenheit (16.7 degrees Celsius), weighed in the air using brass weights).
The fluid ounce is a volume measurement equivalent to 1/16 of a pint or 1/8 of a cup in the United States. The fluid ounce is commonly called a “ounce,” but it is not to be confused with the mass unit. Although one fluid ounce is slightly less than 29.6 millilitres, one fluid ounce is rounded to exactly 30 ml in nutrition labelling.
The fluid ounce is a volume measurement unit used in the United States. Fluid ounces are abbreviated as fl oz, and they’re also known as fl. oz. or oz. fl. 10 fluid ounces, for example, can be written as 10 fl oz, 10 fl. oz., or 10 oz. fl. oz.
Ounce
The ounce refers to a number of various mass, weight, and volume quantities, and it is derived practically intact from the uncia, an Ancient Roman unit of measurement.
The avoirdupois ounce (28.349523125 g) is 1/16 of an avoirdupois pound and is used in the United States and the United Kingdom. It is primarily used in the United States to measure packaged foods and food portions, postal items, the areal density of fabric and paper, boxing gloves, and other items, but it is also used in other parts of the Anglosphere on occasion.
Although the avoirdupois ounce is the most widely used unit of measurement, precious metals such as gold, silver and others are measured in troy ounces, which weigh exactly 31.1034768 g.
‘Ounce’ is also a term used in other purposes:
The ounce force is a unit of force measurement (see below).
The fluid ounce is a volume measurement.
Historically, several ounces measuring mass or volume were used in various countries by various trades and at various eras in history.

Conversions between cups and fluid ounces are shown in the tables below (fl oz). If you’re looking for weight conversions in dry ounces, a chart and information can be found further down the page.
Cups to ounces dry
It’s vital to remember that a cup is a unit of volume, whereas a dry ounce (oz) is a unit of weight when converting between cups and dry ounces (oz). This means that converting a material requires an additional element – the density of the substance. Because olive oil is a denser substance, a cup full of sugar will weigh less than a cup full of olive oil, as an example.

Is there a difference between US and UK fluid ounces?
The pint in the United Kingdom is 20 fluid ounces, while the pint in the United States is 16 fl oz. However, fluid ounces do not equal one another across the Atlantic, thus this translation is not straightforward. Here’s how the two countries compare in terms of volume: The US Customary fluid ounce is 29.573 millilitres, while the British Imperial fluid ounce is 28.413 millilitres. The Imperial pint measures 568.261 millilitres (20 fluid ounces), while the US Customary pint measures 473.176 millilitres (16 fl oz).
