The Gallon Conundrum: American vs Australian Gallons

We’ve all heard of gallons, but what exactly does a gallon mean? Is it different in different parts of the world? In this blog, we’ll dive deep into the fascinating world of gallons, decipher the differences between American and Australian gallons, and learn how to convert litres to Australian gallons. So buckle up, my friends, it’s time to get technical with gallons!

What is a gallon?

Let’s start at the beginning. A gallon is a unit of measurement for volume that is used primarily in the United States and a few other countries. It’s defined as the volume of a cube that is 8 inches on a side, which is equal to 3.785 litres. A gallon can be used to measure liquids, as well as dry goods like grains and vegetables. In the US, a gallon is equal to four quarts, or 128 fluid ounces.

American vs Australian Gallons

While the definition of a gallon is the same in both the United States and Australia, the actual volume of a gallon can differ between the two countries. In the US, a gallon is equal to 3.785 litres, while in Australia, a gallon is equal to 4.546 litres. This means that an Australian gallon is about 20% larger than an American gallon. This can be a tricky difference to navigate if you’re travelling or doing business between the two countries, so make sure you’re clear on which type of gallon is being used!

Conversion from Litres to Australian Gallons

Now that we know the difference between American and Australian gallons, let’s talk about how to convert litres to Australian gallons.

How many litres in a gallon

The conversion factor is simple: one Australian gallon is equal to 4.54609 litres. So, to convert litres to Australian gallons, you simply divide the number of litres by 4.54609. For example, if you have 20 litres of water, the conversion would be 20 ÷ 4.54609 = 4.398 Australian gallons.

So there you have it! Gallons may seem like a simple unit of measurement, but they can be deceptively complex. Always make sure you know whether you’re dealing with an American or Australian gallon, and don’t forget your conversion factor if you’re working with litres! With this knowledge in hand, you’re now ready to take on the world of gallons with confidence and ease.
