How to convert gal to L
Household paint is commonly sold in gallon cans in the US and in litre quantities (typically 2.5 L or 5 L) almost everywhere else. A US gallon can (3.785 L) sits awkwardly between the two common metric sizes, which is one reason painting coverage estimates ("one gallon covers 400 square feet") do not translate cleanly into a metric equivalent without a real conversion.
The US gallon is defined as 231 cubic inches exactly, an oddly specific figure with roots in 18th-century English wine-trade measures (the "Queen Anne gallon" of 1707) that the US retained even after England itself moved to the larger imperial gallon in 1824. The 3.78541-litre figure is simply what 231 cubic inches works out to once the inch is defined in metric terms.
