Fluid ounce
Definition: A fluid ounce (symbol: fl oz) is a unit of volume in the imperial and United States customary systems of measurement. The US fluid ounce is 1/16 of a US fluid pint, and 1/128 of a US liquid gallon, which is equal to 29.57 mL. The imperial fluid ounce is 1/20 of an imperial pint, and 1/160 of an imperial gallon, which is equal to 28.4 mL.
History/origin: The fluid ounce was originally based on the volume occupied by one ounce (weight) of a given liquid such as wine or water, thus varying based on the system being used. In 1824, the imperial gallon was defined as the volume of ten pounds of water at a temperature of 16.7°C. The imperial gallon's definition was later changed to be equal to 4.54609 liters, making the imperial fluid ounce equal to exactly 28.4130625 mL.
The United States fluid ounce was initially based on the wine gallon used in England prior to 1824. After the adoption of the international inch in 1959, the US fluid ounce became equal to exactly 29.5735295625 mL.
Current use: As the name indicates, the fluid ounce is typically used as a measurement of liquid volume. It is mostly used in the United States and the United Kingdom, as one of the many measurements of volume used.
Cup (US)
Definition: A cup is a unit of volume in the imperial and United States customary systems of measurement. The metric cup is defined as 250 milliliters. One United States customary cup is equal to 236.5882365 milliliters as well as 1/16 U.S. customary gallons, 8 U.S. customary fluid ounces, 16 U.S. customary tablespoons, or 48 U.S. customary teaspoons.
Current use: The cup is typically used in cooking to measure liquids and bulk foods, often within the context of serving sizes. Actual drinking cups can vary significantly in terms of size and are generally not a good representation of this unit. Standardized measuring cups are used instead.
