### 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.

### Quart

Definition: The quart (symbol: qt) is a unit of volume in the United States customary and imperial systems of measurement. Multiple definitions of the quart exist. In the US, a liquid quart is equal to approximately 0.946353 liters and a dry quart is equal to approximately 1.101221 liters. In the UK, the imperial quart is equal to 1.136523. In both the UK and the US, the quart is equal to ¼ of its respective gallon.

History/origin: The quart is based on the gallon, the definition of which has changed throughout history based on the commodity being referenced. The current definition of the US quart is based on the English wine gallon. This same definition was used for the imperial quart up until 1824 when the UK re-defined the imperial gallon.

Current use: The respective versions of the quart are used mainly in the United States and the United Kingdom, though in the UK, the use of the liter is now mandated as a result of metrication.
