Formula
US gallons = litres ÷ 3.785411784
This page uses the US liquid gallon, exactly 3.785411784 litres. The imperial gallon used in the UK is about 4.54609 litres, so an imperial gallon is larger. Fuel sold in Canada and the UK is often priced per litre, not per imperial gallon.
A 50 litre tank
50 ÷ 3.785411784 = 13.209 US gallons. At a station that prices fuel per gallon, multiply the gallon price by 13.209 to estimate a full 50 litre fill.
A 50 litre fuel tank holds 13.209 US gallons. A US gallon of milk is 3.785 litres, so a 4 litre jug is a little more than a gallon. Do not use this result for UK miles-per-gallon comparisons without switching to imperial gallons: an imperial gallon is roughly 1.201 US gallons. The word “liter” in the page title matches the spelling people type; the definition is the litre.
