What is Gallon ?

hi

the gallon (/ˈɡælən/) is a unit of measurement for volume and fluid capacity in both the US customary units and the British imperial systems of measurement. Three significantly different sizes are in current use: the imperial gallon defined as 4.54609 litres (4 imperial quarts or 8 imperial pints), which is used in the United Kingdom, Canada, and some Caribbean nations

the imperial gallon defined as 4.54609 litres (4 imperial quarts or 8 imperial pints), which is used in the United Kingdom, Canada, and some Caribbean nations; the US gallon defined as 231 cubic inches (4 US liquid quarts or 8 US liquid pints) or about 3.785 L, which is used in the US and some Latin American and Caribbean countries; and the least-used US dry gallon

The gallon currently has one definition in the imperial system, and two definitions (liquid and dry) in the US customary system. Historically, there were many definitions and redefinitions.

the imperial (UK) gallon, now defined as exactly 4.54609 litres (about 277.42 cubic inches), is used in some Commonwealth countries and was originally based on the volume of 10 pounds (approximately 4.54 kg) of water at 62 °F (17 °C). The imperial fluid ounce is defined as160
of an imperial gallon; there are four quarts in a gallon, two pints in a quart, and 20 imperial fluid ounces in an imperial pint.

This dry measure is one-eighth of a US Winchester bushel of 2150.42 cubic inches; it is therefore equal to exactly 268.8025 cubic inches or about 4.405 L. The US dry gallon is not used in commerce, and is not listed in the relevant statute, which jumps from the dry quart to the peck.[7]

Gallons used in fuel economy expression in Canada and the United Kingdom are imperial gallons.

A gallon is a measure of volume primaririly used in the USA. Most commonly a gallon refers to a US gallon but there are two other gallons out there: imperial gallon - used in the UK and dry gallon mostly used in agriculture (for grapes, apples, berries, etc.)

US gallons are used in the USA and in some Latin American countries. Imperial gallons are no longer the offical measure for volume but many people still use it. In other parts of Eurore liters are used and gallons are not commonly understood. Canada, being a Commonwealth country and bordering the US uses liters officially but most people are good with gallons.

It all comes down to the small print. If the milk-chug challenge is to keep a gallon of the white stuff down (and frankly, this is not recommended, in spite of how much calcium it might contain), then the definition of 'gallon' becomes quite important.

But why is it that you say potato, and we say potatoh? Why is 'football' one sport over here and a totally different one over there? Why is a gallon not a gallon? Am I even real any more, or just an animation of a reflection of a hologram?

Way back - at the time we all lived together - we had used the Queen Anne's gallon of 3.785l to measure wine. We also had different volumes and names to measure both beer and grain. When we realised that this was silly, in 1824, the UK chose a single imperial term and lumped together all three measurements, picking a roughly-average volume and calling it a gallon. American colonists, though, stuck to tradition and kept just the Queen Anne's volume for their own gallon definition.

A ten-gallon hat does not hold ten gallons. It's actually from the Spanish galón, which means braid or plait, and is named for the decoration around the hat.

The world's largest boiling river must be a great place to cook eggs without increasing your energy bills. Based in the unspellable Deildartunguhver, Iceland, these hot springs spurt out 245 litres (54 UK gallons / 65 US gallons) of scalding hot water every single second.

The largest smoothie ever produced was an effort by Cabot Creamery Cooperative, who used 3200 bananas and a lot of ice and yoghurt to make 1514.15 liters of beverage. Members of the public pitched in by pedalling the bicycles that powered the blenders, resulting in 400 US gallons, or 333 UK gallons of delicious banana smoothie (that fortunately, nobody was forced to drink within 60 minutes).

The most expensive liquid in the world is apparently scorpion venom, which retails (where? Walmart?!) at $38,858,507.46 per US gallon. Best wait until Black Friday to stock up for next year.

The US gallon is legally defined as 231 cubic inches, which is exactly 3.785411784 litres. A US liquid gallon of water weighs about 8.34 pounds or 3.78 kilograms at 62 °F (17 °C), making it about 16.6% lighter than the imperial gallon.

There are four quarts in a gallon, two pints in a quart and 16 US fluid ounces in a US pint, which makes the US fluid ounce equal to

In order to overcome the effects of expansion and contraction with temperature when using a gallon to specify a quantity of material for purposes of trade, it is common to define the temperature at which the material will occupy the specified volume. For example, the volume of petroleum products and alcoholic beverages are both referenced to 60 °F (15.6 °C) in government regulations.
