# Convert liter to ounces

Please provide values below to convert liter [L, l] to fluid ounce (US) [fl oz (US)], or *vice versa*.

### Liter

**Definition:** A liter (symbol: L) is a unit of volume that is accepted for use with the International System of Units (SI) but is technically not an SI unit. One liter is equal to 1 cubic decimeter (dm^{3}), 1,000 cubic centimeters (cm^{3}), or 1/1,000 cubic meters (m^{3}).

**History/origin:** There was a point from 1901 to 1964 when a liter was defined as the volume of one kilogram of pure water under the conditions of maximum density at atmospheric pressure. However, due to the mass-volume relationship of water being based on a number of factors that can be cumbersome to control (temperature, pressure, purity, isotopic uniformity), as well as the discovery that the prototype of the kilogram was slightly too large (making the liter equal to 1.000028 dm^{3} rather than 1 dm^{3}), the definition of the liter was reverted to its previous, and current definition.

**Current use:** The liter is used to measure many liquid volumes as well as to label containers containing said liquids. It is also used to measure certain non-liquid volumes such as the size of car trunks, backpacks and climbing packs, computer cases, microwaves, refrigerators, and recycling bins, as well as for expressing fuel volumes and prices in most countries around the world.

### 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.
