Why is there difference in US gallon and UK gallon?

Answer 1

Who knows?

Historically, each town and city had their own units. As cities became countries, these units were partially reconciled and each nation had a number of different units.

There have been dozens of different gallons over the years. Many of these fell into disuse over time, and many more were dumped with the introduction of the metric system into all countries except the US.

At the present time there is only gallon in wide use, the US liquid gallon at 231 cubic inches. But there is also the US dry gallon at 269 cubic inches. The Imperial (UK) gallon is is 277 cubic inches or as British people would better understand, 8 pints. The Imperial gallon is no longer as widely used since European Union legislation ruled that when products were sold this must be in metric measures. The British have however resisted this and despite fuel become sold at the pump in litres, cars still are assessed for fuel consumption in miles per gallon and products sold with an imperial equivalent.

Answer 2

1 UK gallon is approximately equal to 1.2 US gallon. Note that it is 1.2 US Liquid gallon. US gallon is further divided into US liquid gallon and US dry gallon (historically used to measure volume of grains). Because of so many different definitions and difficult conversions, most of the countries have adopted the SI units.

Answer 3

The US gallon is smaller than the UK gallon because they are based on different units of measurement. The US gallon is based on the wine gallon, while the UK gallon is based on the ale gallon. Additionally, the US and UK gallons are defined differently, with the US gallon being defined as 231 cubic inches and the UK gallon as 277.42 cubic inches.
