How this is calculated
gal = liters ÷ 3.785411784 (exact — US gallon)
The fuel-receipt direction: a 50 L fill-up is 13.21 US gallons, a 200 L rain barrel is 52.83 gallons, a 2 L soda bottle is 0.53 gallons. These are US gallons; the old imperial gallon is 4.546 L — a fifth bigger — and mixing them up is the classic fuel-economy blunder.
The US gallon is defined as exactly 231 cubic inches = 3.785411784 L (exact via the inch). UK pumps sell liters but quote economy in miles per imperial gallon — two gallons, one word, always check which.
Frequently asked questions
How many gallons is 1 liter?
0.264 US gallons. Flip it for the anchor everyone remembers: 1 US gallon = 3.785 L.
US or imperial gallons here?
US (3.785 L). The imperial gallon (4.546 L) survives in UK fuel-economy figures and older Commonwealth documents — 20% bigger, so a “40 mpg” UK car and a “40 mpg” US car are not equally frugal.
What is a 55-gallon drum in liters?
The US 55-gal drum holds 208 L. The petroleum barrel (bbl) is a different measure — 42 US gal = 159 L — units that coexist confusingly in the same industries.
How many liters in a US fuel tank?
Compact cars run 38–50 L (10–13 gal); pickups 80–140 L (21–37 gal). Convert your fill-up receipt and the tank spec sheet with the same exact factor above.
