Step-by-Step Examples
Example 1
Full Tank
50 liters fuel to US gallons.
- 50 x 0.2642 = 13.21 US gal
- Common in Canada where fuel is priced in liters
✓ 13.21 US gallons
Example 2
Water Jug
5 liters to US gallons.
- 5 x 0.2642 = 1.321 US gal
- Standard 5L water jug is about 1.32 US gallons
✓ 1.32 US gallons
Example 3
UK Beer
568 ml pint to US equivalents.
- 0.568 L x 0.2642 = 0.150 US gal = 19.2 fl oz
- US pint = 16 fl oz; UK pint = 20 fl oz (568 ml)
✓ 0.15 US gallons / 19.2 fl oz

Common Mistakes to Avoid
⚠️
US gallon vs Imperial gallon
US gallon = 3.785 L; UK Imperial gallon = 4.546 L. They are NOT equal. Using the wrong gallon type causes 20% errors in fuel calculations.
⚠️
Confusing mL and L
1,000 mL = 1 L. A 500 mL bottle = 0.5 L = 0.132 US gallons. Don't convert mL as if they were L.
⚠️
Fuel consumption direction
European fuel economy is listed in L/100km. US is mpg. These require different formulas - a simple liters-to-gallons conversion doesn't directly convert fuel economy.
