$/gal
per US gallon
Cost per volumeexact by definition
Cost per US gallon is the retail fuel and bulk liquid price in the United States. A US gallon is exactly 3.785411784 litres, so one dollar per US gallon is exactly 264.1720523581484 dollars per cubic metre, rounded here only in its decimal form. The conversion is exact, resting on the exact definition of the US gallon as 231 cubic inches.
Watch out: The imperial gallon is 4.54609 litres, about 20 percent larger, so a price per imperial gallon converts differently. Fuel prices from the United Kingdom, and older Canadian figures, may be on the imperial gallon.
