Gallon vs Litre
Gallon and litre are units for measuring a material’s volume. Nowadays, most substances such as water and other beverages are packed by litre or by gallon, which is probably why people would often refer to a container as “a litre” or “a gallon” of which.
Gallon first started out during the early 19th century as a term to refer to standard distribution packaging of corn harvest and wine. Over the years, it has been adapted into new definitions according to the liquid or solid substance which it describes. Currently, its standard definition has been split into three: 4.5L for the UK gallon, 3.8L for the US liquid gallon and 4.4L for the US dry gallon.
Litre used to be an official unit of volume in the French metric system. Now, it is frequently used in all measurement applications despite the fact that it is not an official volume unit of the SI, which is cm3 (cubic centimeter). One litre is equal to 1000 cm3. The use of the litre unit first began in France, after which it was adapted internationally to be used as a standard unit of many product packagings.
Difference between Gallon and Litre
The volume of 1 gallon is actually greater than the volume of 1 litre. To be specific, 1 gallon is equal to 4.5 litres (in the UK), 3.8 litres (for liquid substances in the US) and 4.4 litres (for solid substances in the US). The gallon unit of measurement started out as a French standard unit of volume. On the other hand, the litre unit of measurement started out as a standard unit of volume in the US. While both are used as customary packaging dimensions in the industry, the litre is used more often for commodities that need to be bought in smaller quantities than the gallon.
