What is a gallon (UK)?

A gallon (UK), also called the imperial gallon, is exactly 4.54609 litres and is used mainly in regions and contexts where imperial units are employed.

What does barrel (oil) measure?

Barrel (oil) is a non-SI volume unit used in the petroleum industry equal to 42 US gallons, commonly used to express volumes and flow rates of crude oil and petroleum products.

Why is it important to differentiate between gallon (UK) and US gallon?

Because the gallon (UK) and US gallon are different units, mixing them without proper conversion can cause significant measurement errors.
