Formula: mpg (US) = 235.214583 ÷ L/100km. Open the live calculator to convert any value.
Formula
mpg (US) = 235.214583 ÷ L/100km
MPG (US) = 235.215 / (L/100 km). The same constant works in both directions because the units are reciprocals. For imperial MPG, divide 282.481 by L/100 km instead.

Background
Most of the world reports fuel use in L/100 km. The US, UK, and a handful of Caribbean countries use MPG. When you see a European car review citing 5.5 L/100 km, that's about 42.8 US MPG, which is competitive but not class-leading for a small gasoline car in 2026.
Common use cases
- Translate European-style fuel economy figures into US mpg for shopping or travel decisions.
- Compare a fuel report in L/100km with US spec sheets and owner discussions.
- Reuse common values like 5, 6, or 8 L/100km without applying the inverse formula by hand.
Frequently asked questions
Is lower or higher better for L/100 km?
Lower is better. L/100 km measures fuel consumption per fixed distance, so a smaller number means a more efficient car.
Is the conversion exact?
The constant 235.215 is accurate to six significant figures; it derives from exact definitions of the gallon and the mile.
How do EV efficiency numbers compare?
EVs report kWh/100 km or miles per kWh instead of MPG / L/100 km. The EPA also publishes 'MPGe' for EVs by converting electricity to gasoline-equivalent energy. The conversion factor is 33.7 kWh per gallon of gasoline.
Why don't EU cars list MPG?
L/100 km has been the standard fuel-economy unit in the EU for decades because it scales linearly with consumption and aligns with metric road distances.
