*Science Trends page,*each country has its own size in determining the amount that is adjusted to the shape, type, and brand of the gallon itself.

**What does gallon of water mean?**

**Gallon and liter: what are the differences?**

Iiters and milliliters are the most used volume measurement units, but gallons can be mentioned, especially when dealing with large volumes. The equivalents are as follows:

- 1 US gallon = 3.8 liters
- 1 US dry gallon = 4.40488 liters
- 1 British gallon = 4.5 liters

The imperial measurement system is the most widely used measurement system in the United States. In terms of volume, the gallon is the unit of measurement for imperial volumes, while the liter is used to measure volumes in the metric system, which is used in most parts of the world.

**The imperial gallon**

The imperial or British gallon is a unit of measurement containing exactly 4.54609 liters or 277.42 cubic inches. It is common in Commonwealth countries and some Caribbean states.

The imperial gallon was originally based on 10 pounds, which equals 4.54kg of water at 17°C. Imperial ozone weighs 1⁄160 of the imperial gallon.

An imperial gallon is divided into four pints, each pint is made up of two pints, and each pint is made up of 20 imperial fluid ounces.

**US Liquid Gallon**

A US gallon is defined as 3.7854 liters or 231 cubic inches. At 62°F (17°C), one gallon of liquid water in the United States is equal to 3.78 kg or 8.34. It is 16.6% lighter than the imperial gallon.

However, just like the imperial gallon, a US gallon is divided into four pints, each pint is divided into two pints, and each pint contains 16 US fluid ounces. Therefore, it takes 128 US fluid ounces to fill a US fluid gallon.

It is common to specify the temperature at which the material will weigh or occupy a particular volume.

This is done to overcome the change in volume or mass resulting from the change in temperature.

In the United States, the weight of alcoholic and petroleum products is defined as 60°F (16°C).

**US dry gallon**

The US dry gallon is equal to eight liters of the Winchester bushel, 268.8025 cubic inches or 4.4.5.

1 Gallon [Fluid, US] = Liters 3.7854118

1 Gallon [Dry, US] = Liters 4.4048838

1 Gallon [UK] = Liters 4.54609

**Global Gallon Usage**

The imperial gallon was used in the UK until 1994. Fuel economy, in particular, ran on gallons in Canada, the UK and the US.

European Directive 80/181/EEC of December 31, 1994 banned the continued use of the gallon for commercial and official purposes in favor of the litre. However, the gallon could still be used as a secondary unit of measurement.

On September 30, 1995, the United Kingdom changed its laws and adopted the litre. Several states in the Caribbean and South America still use the gallon.

In 2010, the United Arab Emirates adopted the use of liters and started selling petroleum products in liters. In 2015, the states of Antigua and Barbuda also switched to the litre.

**Conversion of gallons as units of volume**

So, before you get confused about the meaning of the word gallon here, it needs to be explained first. As is known, a gallon is a measure or measure of liquid goods, such as water, gasoline and others.

However, this meaning has a slightly different meaning in some countries. For instance, gallon in Indonesia is a place to store bottled water.

In fact, a gallon is a unit of measure, not the name of an object such as a gallon of mineral water or other terms in Indonesia.

As previously explained that one gallon in the United States contains about 3.785 liters and in the UK one gallon equals 4.546 liters. So, it’s different, *guys*, the calculation of gallons in Indonesia is with the US and UK.

So, if asked how many liters are in one gallon in Indonesia, for example with the Aqua brand, it is equivalent to five gallons in the United States.

One gallon of the Aqua brand contains 19 liters and usually uses plastic material that can be filled repeatedly.

**Why convert from gallons to liters?**

Due to globalization, conversions are influenced by the United States, particularly in terms of its measurements and the information it receives. Thus, you may have to refer to a US document that uses gallons as a unit of measurement. You will then have to convert this volume in gallons to a volume in liters. Also, Canadians themselves sometimes use both units of measurement and may find it useful to convert gallons to liters and liters to gallons.
