Frequently Asked Questions
How many MPG is 1 L/100km?
1 L/100km = 100 km/L, which converts to approximately 235.2 MPG(US). Lower L/100km means better fuel economy, while higher MPG means better fuel economy.
What is the difference between MPG(US) and MPG(UK)?
A US gallon equals 3.785 liters, while a UK (imperial) gallon equals 4.546 liters. So for the same MPG number, the UK MPG covers about 20% more distance. 1 MPG(US) ≈ 1.2 MPG(UK).
How do I calculate fuel consumption in L/100km?
Fuel consumption (L/100km) = Fuel used (liters) ÷ Distance traveled (km) × 100. For example, if you used 40 liters to drive 500 km, consumption = 40 ÷ 500 × 100 = 8 L/100km.
How do I convert US MPG to L/100km?
Formula: L/100km ≈ 235.214 ÷ MPG(US). For example, a car rated at 30 MPG(US) has fuel consumption ≈ 235.214 ÷ 30 ≈ 7.84 L/100km.
