The quick rule for your head
Divide by 4 and add 5%: 40 L ÷ 4 = 10, plus 0.5 ≈ 10.6 gallons (exact: 10.57). For fuel tanks the anchor pair is 50 L ≈ 13 gallons. If a figure seems 20% off from what a British source says, that is the imperial gallon talking — check which gallon before doubting the maths.
Where this conversion shows up
Fuel dominates: tank sizes, fuel economy and price comparisons between US-gallon and litre countries all cross this line. Aquariums are the quiet second — American tank sizes in gallons against European ones in litres — followed by anything American with engine displacement or liquid capacity in its spec sheet.
