In many countries of the world, the SI metric system has long been used. In it, the main unit of measure, for example, is the length of the meter, time is usually measured in seconds, weight - in grams. And the unit of volume, depending on the situation, is either a liter or a cubic meter.
However, this is not the case in countries that have not adopted the SI system. So, in some states use the English measure of quantities. These countries include the United Kingdom, the USA, Cuba and Argentina directly. In addition, there are a number of states that use such a system of measures only partially.
In the five countries listed, a gallon is used as the unit volume. However, the main minus of all unified measurement measures is their absolute inaccuracy and the presence of a number of discrepancies. For this reason, when answering the question of how many liters are in one gallon, it is necessary to first clarify which one. Since such measures in the USA, Britain and other countries are very different from each other.

In addition, there is such a thing as a proof-gallon, which serves as a standard for all other units of measurement. This measure is 1.89 liters.
