Answer first
How do you convert MPG to L/100 km?
The MPG to L/100 km converter transforms the US distance-per-fuel metric into the European consumption-per-distance standard. L/100 km is the default unit on vehicle labels across the EU, Canada, and Australia. This tool helps you compare American and European vehicle specs side by side.

How it works
MPG to L/100km Calculator: inputs, formula, and result
Unlike direct conversions, this calculator flips a distance-per-volume metric into a volume-per-distance metric. It divides exactly 235.215 by your provided MPG to output the liters required to travel 100 kilometers.
Formula
L/100 km = 235.215 ÷ MPG
Worked example
A vehicle rated at 30 MPG consumes 235.215 ÷ 30 = 7.84 L/100 km.
Pro tip: Lower L/100 km means better efficiency, the opposite of MPG where higher is better. A car using 5 L/100 km is more efficient than one using 8 L/100 km.

What changes the result for MPG to L/100km?
Your input MPG is the sole variable. Real-world economy shifts based on idle time, rapid acceleration, and the use of air conditioning, which all impact the baseline MPG. Traffic, tire pressure, vehicle load, terrain, driving style, weather, fuel price, and the quality of the input data can change the final result.

FAQ
FAQs about MPG to L/100km
3 questions
Question 1 of 3 is open
Why is L/100 km an inverse measure compared to MPG?
MPG measures distance per unit of fuel (higher = better), while L/100 km measures fuel consumed per distance (lower = better). They are mathematically inverse: L/100 km = 235.215 ÷ MPG.
What L/100 km is considered good for a car?
For a passenger car, 5-7 L/100 km is excellent, 7-9 is average, and above 10 is poor. Hybrids can achieve 3-5 L/100 km, while large SUVs may use 12-15 L/100 km.
Does Canada use L/100 km or MPG?
Canada officially uses L/100 km on vehicle fuel economy labels (NRCan ratings), though some Canadians informally reference US MPG due to cross-border vehicle shopping.
