$/imp gal
per imperial gallon
Cost per volumeexact by definition
Cost per imperial gallon, the imperial gallon being exactly 4.54609 litres. It appears in older Canadian, British and Caribbean fuel and water pricing. The conversion is exact, since the imperial gallon is exactly defined and only the volume is converted.
Watch out: An imperial gallon is about 20 percent larger than a US gallon, 4.546 litres against 3.785. Fuel economy figures in miles per gallon carry the same trap, which is why a British and an American figure for the same car differ by that fifth.
