Why do some countries use MPG and others use L/100km?
Measurement systems differ by region. MPG is common in the US/UK, while L/100km is widely used in Europe and many other countries.
Convert between L/100km and MPG units instantly. Perfect for comparing fuel efficiency across different regions.

MPG = 235.21 ÷ L/100kmL/100km = 235.21 ÷ MPGOur fuel consumption converter makes it easy to switch between L/100km and MPG units. This is essential when comparing vehicles from different regions or understanding fuel efficiency ratings in various measurement systems.
The conversion factor of 235.21 is derived from the relationship between US gallons, liters, miles, and kilometers, ensuring accurate conversions between these two systems.
Use 235.21 divided by MPG to convert MPG to L/100km, and 235.21 divided by L/100km for the reverse conversion.
Higher MPG means better efficiency, while lower L/100km means better efficiency. Both represent the same performance in different standards.

Higher MPG is better. Lower L/100km is better. They are inverse representations of the same fuel efficiency performance.
Yes. Convert the efficiency unit first, then use a fuel cost calculator with your local fuel price for accurate trip budgeting.
A good fuel economy number depends on vehicle class, powertrain type, and real-world driving conditions. Compact hybrid cars can exceed 45 MPG (around 5.2 L/100km), while larger SUVs and trucks typically return lower MPG and higher L/100km values. The key is comparing similar vehicle categories instead of comparing all vehicles directly.
Use this converter to normalize efficiency units first, then compare models with similar body type, drivetrain, and intended usage. This gives a more accurate picture for ownership planning, especially if you are deciding between city-focused and highway-focused vehicles.
50+ MPG or below 4.7 L/100km
30-49 MPG or 4.8-7.8 L/100km
Below 30 MPG or above 7.9 L/100km
Fuel efficiency directly impacts long-term ownership cost. Even small differences in MPG or L/100km can add up to significant annual savings when multiplied by your yearly mileage and current fuel prices. This is especially important for commuters, frequent travelers, and fleet operators.
Converting to your preferred unit helps you estimate fuel spend more accurately and avoid misunderstandings when reading international specifications. After converting, pair your result with local fuel price and yearly distance to estimate monthly and annual fuel budget.
