What is a gallon?
The gallon has a fascinating history, with many different definitions and redefinitions throughout the years.
Gallon (abbreviation 'gal') is a unit of volume used in the USA and some Latin American and Caribbean countries.
You might be surprised that there are different types of gallons. Royal gallon is scarcely found in the United Kingdom; they still use an imperial measurement system along with a metric system.
US dry gallon is equal to ⅛ US bushel or 4.4 L. Therefore, it is about 14.1% bigger than the US fluid gallon.
Interestingly, Canadians consider the debate liter and gallon as standard units.
American gallon vs. Imperial gallon
US gallon is a standard unit for measuring volume in America. The conversion system says that a gallon equals 3.78 liters or 16 cups.
1 US gallon = 16 US cups
1 US gallon = 3.78 liter
1 US gallon = 231 cubic inches
Imperial gallon (aka British or Royal gallon) is 20% more than US gallon and equals 4.546 liters.
1 British gallon = 1.2 US gallon
1 British gallon = 4.546 liters
It is essential to distinguish between the US customary gallons and Royal gallons. Why?
Because the US gallon is smaller than the UK one, meaning that if purchasing a gallon at home or abroad, then expect to have less remaining after purchase.
