Facts about Cup (unit)

Basic facts: The cup (unit) is a measure of volume in cooking in the United States customary and imperial systems of measurement. The metric cup is represented as 250 milliliters. 1 US customary cup is equivalent to 236.5882365 milliliters as well as 1/16 US customary gallons, 8 US customary fluid ounces, 16 US customary tablespoons, or 48 U.S. customary teaspoons.

Use: As mentioned above, the cup (unit) is commonly used in cooking to measure liquids and bulk foods, often on the subject of serving sizes [serving size, also known as the portion size is the amount of a drink or food that is commonly served]. In terms of size, actual drinking cups can differ significantly and are generally not a good indication of this unit. Instead, standardized measuring cups are used.

Facts about Fluid Ounce

Basic facts: A fluid ounce [symbol: fl oz] is a unit of volume in the United States customary and imperial systems of measurement. The United States fluid ounce is 1/16 of a US fluid pint, 1/128 of a US liquid gallon, which is equivalent to 29.57 mL. The imperial fluid ounce is 1/20 of an imperial pint, and 1/160 of an imperial gallon, which is equivalent to 28.4 mL.

History: The fluid ounce was initially based on the volume occupied by one ounce [weight] of a given liquid like water or wine, accordingly varying based on the system being used. In 1824, the imperial gallon was represented as the volume of ten pounds of water at a temperature of 16.7°C. The definition of the imperial gallon was later changed to be equivalent to 4.54609 liters, which made the imperial fluid ounce equivalent to exactly 28.4130625 mL.

Initially, the United States fluid ounce was based on the wine gallon used in England before 1824. In 1959 after the adoption of the international inch, the U.S. fluid ounce became equivalent to exactly 29.5735295625 mL.

Use: As the name shows, the fluid ounce is generally used as a measurement of liquid volume. As one of the many measurements of volume, it is mainly used in the United States and the United Kingdom.
