How it's calculated
A US gallon equals 3.785411784 liters. To convert liters to gallons, divide by that factor; to convert gallons to liters, multiply by it.
gallons = liters ÷ 3.785411784
Common when comparing the fuel economy of a car imported from the US (miles per gallon) with the figure typically used in Europe (liters per 100 km), or when reading tank and container capacities in American sources.
liters = gallons × 3.785411784
A typical US car's fuel tank (12-16 gallons) equals roughly 45 to 60 liters, similar to an average European car's tank.
Worked example
50 liters equals 50 ÷ 3.785411784 ≈ 13.21 gallons. A car rated at 30 mpg (miles per gallon) uses roughly 7.8 liters per 100 km.
