### 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.

### Milliliter

Definition: A milliliter (symbol: mL) is a unit of volume that is accepted for use in the international system of units (SI). One milliliter is equal to 1 cubic centimeter (cm3), 1/1,000,000 cubic meters (m3), or 1/1000 liters.

History/Origin: The base unit of the milliliter is the liter (US spelling), spelled "litre" in SI terms. The term "litre" was originally part of the French metric system and was derived from the term "litron," one of the older versions of the French litre. Refer to the liter page for further details.

Current use: Milliliters are used to measure the volume of many types of smaller containers in everyday use, such as plastic bottles, cans, drinking, glasses, juice and milk cartons, yogurt, toothpaste tubes, perfume/cologne bottles, etc. Many measurement devices such as graduated cylinders, beakers, pipettes, measurement cups, etc. also use the measurement of milliliters.
