About Imperial fluid ounce (imp fl oz)
The imperial fluid ounce (imp fl oz) is a unit of volume equal to one twentieth of an imperial pint, approximately 28.413 milliliters. It is used in the United Kingdom and Commonwealth countries, though metric units have replaced it in most commercial contexts. The imperial fluid ounce is slightly smaller than the US fluid ounce (29.574 mL). UK spirits measures are now defined by law in 25 mL and 35 mL metric measures, which do not align exactly with the imperial fluid ounce.
A single spirits measure in a UK bar is 25 mL or 35 mL — close to, but not exactly, one imperial fluid ounce (28.41 mL).
About Cubic mile (in³)
A cubic mile (mi³) is the volume of a cube with 1-mile sides, equal to approximately 4.168 trillion liters or about 4.168 km³. It is used in geoscience, hydrology, and environmental science to describe volumes of large water bodies, atmospheric water vapor, volcanic eruptions, and glacial ice. The total volume of Earth's oceans is approximately 320 million cubic miles. The unit is primarily used in US scientific and journalistic contexts.
The Great Lakes together contain about 5,440 mi³ of fresh water. The Amazon River discharges roughly 1.5 mi³ per day.
Imperial fluid ounce – Frequently Asked Questions
Why did the UK abandon the fluid ounce for spirits but keep the pint for beer?
When the UK metricated in the 1990s, spirits measures were switched to 25 mL and 35 mL because publicans needed precise, legally enforceable pour sizes — and optic dispensers were easy to replace with metric ones. Beer, however, had enormous cultural resistance: the "pint" is deeply embedded in British pub identity, and the Campaign for Real Ale lobbied hard. Parliament granted an explicit exemption allowing draft beer and cider to be sold by the imperial pint. Milk got a similar exemption. The result is a hybrid system where your gin is metric but your beer is imperial.
How many imperial fluid ounces are in a UK pint?
There are exactly 20 imperial fluid ounces in one UK pint (568 mL). In the US system, 1 pint = 16 US fluid ounces (473 mL).
Is the imperial fluid ounce still used?
The imperial fluid ounce is rarely used for commercial transactions in the UK today, which metricated in the 1990s. UK spirits servings are now legally defined in metric (25 mL or 35 mL).
Why is a UK shot 25 mL not one fluid ounce?
When the UK metricated bar measures, the 25 mL "metric measure" replaced older imperial measures. One imperial fl oz (28.41 mL) was not adopted because the EU standardized on 25 mL. So UK shots are not exactly one fl oz.
How many milliliters are in an imperial fluid ounce?
One imperial fluid ounce equals approximately 28.413 mL. One US fluid ounce equals approximately 29.574 mL. Both round to roughly "30 mL" in casual usage, but the precise difference matters in pharmacology.
Cubic mile – Frequently Asked Questions
How many liters are in a cubic mile?
One cubic mile equals approximately 4.168 × 10¹² liters (about 4.17 trillion liters) or roughly 4.168 km³. It is used only for planetary or geological scale volumes.
How much water is in the oceans in cubic miles?
Earth's oceans contain approximately 321 million cubic miles (1.335 billion km³) of water. The Pacific Ocean alone accounts for about 170 million cubic miles.
How does a cubic mile compare to a cubic kilometer?
One cubic mile equals approximately 4.168 cubic kilometers (km³). Geoscientists generally use km³; cubic miles appear mainly in US-origin journalism and older literature.
Is the cubic mile used in science?
The cubic mile is used in US-origin geoscience and hydrology texts for Great Lakes volumes, glacier mass loss, and ocean capacity. International scientific literature generally uses km³ instead.
How many cubic miles of water are in the Great Lakes?
The five Great Lakes together contain approximately 5,440 cubic miles (22,671 km³) of fresh water — about 21% of the world's surface fresh water. Lake Superior alone holds about 2,900 mi³.
