How do you convert gallons to liters?
Multiply the number of US gallons by 3.785. For the imperial gallon the factor is 4.546. Always check which gallon is meant: a 20 % gap shows up plainly on a tank of fuel.
liters = US gallons × 3.785US gallons = liters × 0.2642
Where these two units are used
The liter does not belong to the international system, which merely tolerates it: it has been exactly one cubic decimeter since 1964, after sixty years of being defined by the mass of water, which made it twenty-eight parts per million larger.

The US gallon is exactly 3.785411784 liters and the imperial gallon 4.54609 liters since its 1985 redefinition. Both values are exact by definition. Methodology & sources.
Frequently asked questions
US gallon or imperial gallon?
The US one is 3.785 l, the imperial 4.546 l. American sites and recipes mean the first, the UK and Canada often the second. The 20 % gap changes everything on a fuel tank.
Why is an oil barrel 159 liters?
Because it holds 42 US gallons, a standard inherited from whiskey casks reused in the first Pennsylvania oil fields around 1860. The figure owes nothing to the metric system and has never been revised.
How do I read fuel economy in miles per gallon?
Divide 235.2 by the miles per gallon figure to get liters per 100 km. A car rated at 30 mpg uses 7.8 l/100 km. The two scales run in opposite directions.
Why is the US gallon 3.785 liters?
Because it descends from the English wine gallon, fixed at 231 cubic inches by a statute of Queen Anne in 1707. The United States kept it unchanged after independence, while Britain swept away its dozens of local gallons in 1824 in favor of one larger gallon. Those 231 cubic inches work out to 3.785411784 liters, an exact figure rather than a rounded one.
Does a gallon of fuel depend on temperature?
By volume, yes. Gasoline expands by roughly 0.1 % per degree, so between 15 and 30 °C the same gallon carries about 1.4 % less matter. Wholesale trade settles the issue by billing net gallons corrected to 60 °F, that is 15.6 °C, while North American retail pumps usually measure the gross volume as it leaves the nozzle.
