What is a Fluid ounce and a Liter?
The fluid ounce is a unit of volume. The US fluid ounce is defined as 1/128 of a US gallon (approx. 29.57 ml). The Imperial fluid ounce is 1/160 of an Imperial gallon (approx. 28.41 ml).
The liter (symbol L or l) is a metric unit of volume. It is defined as exactly one cubic decimeter (1 dm³), which is equivalent to 1,000 cubic centimeters (cm³) or 0.001 cubic meters (m³). The liter is commonly used for measuring liquids and sometimes granulated solids.
Note: The Fluid ounce is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Liter belongs to the metric (SI) system.
History of the Fluid ounce and Liter
Derived from the ounce unit of weight/mass, adapted to measure the volume of liquids like wine or water.
The liter was introduced in France in 1795 as one of the new 'republican measures' and was defined as one cubic decimeter. The original symbol was 'l', but the symbol 'L' was adopted by the General Conference on Weights and Measures (CGPM) in 1979 to avoid confusion with the number '1'. While not an official SI unit (the SI unit for volume is the cubic meter), it is accepted for use with the SI.

Frequently Asked Questions
Questions About Fluid ounce (fl oz)
Is a US fluid ounce the same as a UK fluid ounce?
No, the Imperial (UK) fluid ounce is slightly smaller than the US fluid ounce (approximately 28.41 ml vs 29.57 ml).
Is a fluid ounce the same as a weight ounce?
No, a fluid ounce measures volume (the space something occupies), while a weight ounce (specifically an avoirdupois ounce) measures mass (how much matter it contains). The relationship between the two depends entirely on the density of the substance being measured. For water, 1 US fluid ounce weighs approximately 1.04 avoirdupois ounces.
About Liter (L)
Is a liter exactly 1 kilogram of water?
Approximately, yes, but not exactly. The original definition of the kilogram was based on the mass of one liter of water at its maximum density (around 4°C). However, the definition of the kilogram has since been refined based on fundamental physical constants. So, 1 liter of water has a mass very close to 1 kg under specific conditions, but it's not the definition.
What is the difference between L and l as symbols for liter?
Both are accepted symbols for the liter. 'L' was officially sanctioned to reduce ambiguity with the numeral '1', especially in print, but 'l' is still commonly used, particularly in scientific contexts where the font makes it distinct.
How does a liter relate to a cubic meter?
1 cubic meter (m³) is equal to 1,000 liters (L). Conversely, 1 liter is equal to 0.001 cubic meters.
