Worked example
A rental car abroad has a 60 L tank. How many US gallons is that?
- 60 ÷ 3.785411784 = 15.85.
- Result: 15.85 gallons.
Price example: fuel at €1.80 per liter is 1.80 × 3.785 = €6.81 per US gallon.

Where liters show up
- Fuel: pumps abroad price per liter; car tanks are listed in liters.
- Drinks: a 2 L soda bottle is 0.528 gal; 1 L is a bit more than a US quart (0.946 L).
- Water cans: a 20 L jerry can is 5.28 gal; a 19 L office water jug is 5 gal.
- Engines: displacement (2.0 L) measures cylinder volume, not fuel.
For fuel economy, convert L/100 km to mpg with the mpg calculator (gas mileage).
Quick mental math
Divide by 4 and add 5%. 40 L ÷ 4 = 10, plus 0.5 = 10.5 gal (exact: 10.57).
