🇬🇧 Gallon meaning: English Vocabulary Flash Card

A gallon is a unit used to measure how much liquid something holds. It’s like a big “container amount” that people use for things such as milk, water, or fuel. In the UK, one gallon is about 4.55 litres, and in the US, one gallon is a little smaller, about 3.79 litres.
