Fuel Consumption Converter — Frequently Asked Questions
Q1 How do you convert US MPG to Liters per 100 km (L/100km)? ▾
Divide 235.215 by your US MPG rating. For example, 30 US MPG equals 235.215 / 30 = 7.84 L/100km.
Q2 Why is UK MPG higher than US MPG? ▾
The UK Imperial gallon is approximately 20% larger than the US liquid gallon (4.546 Liters vs 3.785 Liters), making the UK MPG figure proportionally higher for the exact same vehicle.
Q3 What is considered good fuel economy in L/100km? ▾
Under 6.0 L/100km (approx. 40+ US MPG) is considered very efficient (hybrids/compacts), 6.0 to 8.5 L/100km is moderate, and over 10.0 L/100km is high fuel consumption.
