Fuel consumption: L/100km (AU/EU), MPG (US/UK), km/L (Japan/India). Higher MPG = better, but lower L/100km = better. Inverse relationship makes comparison unintuitive.
The Inverse Relationship
7 L/100km ≈ 33.6 MPG (US) or 40.4 MPG (imp). Small improvements at high consumption save more fuel.
US vs Imperial MPG
US gallon = 3.785 L; imperial = 4.546 L. 40 MPG (imp) ≈ 33.3 MPG (US). Always verify which gallon.

Applications
Vehicle Comparison
5 L/100km ≈ 47 MPG (US). Understanding both helps read international reviews.
Fleet Cost Estimation
8 L/100km × 15,000 km/yr × $1.80/L ≈ $2,160/yr.
Trip Planning
1,500 km at 7 L/100km = 105 L of fuel needed.

Frequently Asked Questions
How do you convert L/100km to MPG?
US: 235.215 ÷ L/100km. 8 L/100km = 29.4 MPG (US). Imperial: 282.481 ÷ L/100km.
How do you convert MPG to L/100km?
US: 235.215 ÷ MPG. 30 MPG = 7.84 L/100km.
What is good fuel economy?
Under 7 L/100km is efficient (petrol). Hybrids: 4–5 L/100km. EVs: 15–20 kWh/100km.
How do I convert fuel consumption data from different countries?
To convert fuel consumption data from different countries, you can use the conversion factors provided by the World Motor Vehicle Manufacturers Association (WMVMA) or the International Organization of Motor Vehicle Manufacturers (OICA). These organizations provide conversion factors for various countries and regions.
How do I calculate fuel economy in different driving conditions?
To calculate fuel economy in different driving conditions, you can use the following formula: Fuel Economy = Total Distance / Amount of Fuel Consumed. You can adjust this formula to account for different driving conditions such as city driving, highway driving, or stop-and-go traffic.
