What is litre?

A litre, symbolized as “L”, is a unit used to measure volume. It is recognized worldwide and comes under the centimetre-gram-second (CGS) system of units. One litre is equivalent to 1000 cubic centimetres (cm3). One litre is also defined as one cubic decimetre. The volume is measured in litres from filling a water bottle to measuring a car’s fuel consumption.

If you are a resident of the United Kingdom, you may need to convert litres to gallons for measuring volume.

What is a gallon?

Apart from litres, a gallon is another popular unit system for measuring volume. The abbreviation of gallon is “Gal”. This metric system is mainly used in the United Kingdom (UK) and the United States (US). 

UK gallon, also known as Imperial Gallon, follows the British Imperial system. The mechanism of calculating the US gallon is different from that of the UK gallon.

1 Imperial gallon = 4.546 litre

1 Imperial gallon = 1.2 * US gallon

How to convert litre to imperial (UK) and US gallon

Use the following formula for the litre to imperial-gallon conversion. 

Imperial gallon (UK) = litres / 4.54609

Here, you are dividing the volume of liquid you want to convert by 4.54609

Now, understand the conversion using a real-time example

If you convert 20 litres of fuel into the UK imperial gallon, you need to divide 20 by 4.54609.

So, the answer will be  = 20/ 4.546 = 4.4 imperial gallon

When you convert the same amount of fuel into a US gallon, the result will be higher as the value of the imperial gallon is higher than the US gallon.

 The formula would be, US gallon = litre / 3.785

For example, if you have 10-litre fuel and you want to convert it into US gallons, the result will be:

US gallon = 10/3.785= 2.64
