How to Convert L/100 KM to MPG (Liter/100 km to Mile/gallon)?

We can convert liter/100 km to mile/gallon by using an example.

Example:

Convert 20 Liter/100 km to Mile/gallon?

We know 1 Liter/100 km = 0.0000043 mile/gallon; 1 Mile/gallon = 235214.5800000 liter/100 km.

20 liter/100 km = ___mpg

20 × 0.0000043 = 0.00009 mpg (we know 1 liter/100 km = 0.0000043 mile/gallon)

Answer:

20 liter/100 km = 0.00009 mile/gallon

Converting L/100km to MPG for US Market Comparison

If you are looking at a European or Australian car review and want to understand the fuel economy in American terms, you need to convert liters per 100 kilometers to miles per gallon. Since both metrics are reciprocals of each other (one measures fuel-per-distance, the other distance-per-fuel), the conversion uses the same constant: 235.215.

  1. Start with the fuel consumption in liters per 100 kilometers.
  2. Divide 235.215 by the L/100km value.
  3. The result is the fuel economy in miles per gallon (US).
  4. Verify: a lower L/100km number should give a higher MPG number.
💡 Tip: European cars often quote combined cycle figures around 5-8 L/100km. That translates to roughly 29-47 MPG — very competitive numbers in the US market.

L/100km to MPG Conversion Table

Typical European fuel consumption ratings and their MPG equivalents for quick reference:

Liter/100 kmMile/gallon
4 L/100km58.8 MPG
5 L/100km47.0 MPG
6 L/100km39.2 MPG
7 L/100km33.6 MPG

Worked Examples: L/100km to MPG

Question 1: A VW Golf is rated at 5.2 L/100km. What is that in MPG?

Solution:

MPG = 235.215 ÷ L/100km

= 235.215 ÷ 5.2

= 45.23 MPG

Answer: 5.2 L/100km = 45.23 MPG — impressive by US standards.

Question 2: A BMW X5 consumes 9.8 L/100km. Convert to MPG.

Solution:

MPG = 235.215 ÷ L/100km

= 235.215 ÷ 9.8

= 24.00 MPG

Answer: 9.8 L/100km = 24.00 MPG — typical for a luxury mid-size SUV.

Question 3: A Renault Clio achieves 4.5 L/100km on the highway. Express in MPG.

Solution:

MPG = 235.215 ÷ L/100km

= 235.215 ÷ 4.5

= 52.27 MPG

Answer: 4.5 L/100km = 52.27 MPG — outstanding highway efficiency.

WLTP vs. EPA: Why Numbers Differ Between Markets

European manufacturers test under WLTP (Worldwide Harmonised Light Vehicles Test Procedure), while US ratings use the EPA cycle. EPA tests are generally more conservative, so the same car may show 6 L/100km in Europe but only achieve the equivalent of 7 L/100km (33.6 MPG) under EPA testing. When cross-shopping, expect 10-20% worse real-world numbers than the WLTP figure suggests.

Fuel Economy Labels Around the World

The EU energy label rates cars from A (best) to G (worst) based on L/100km and CO₂ emissions. Australia uses a similar L/100km sticker. Japan uses km/L (the inverse of L/100km). The US uses a window sticker showing MPG and estimated annual fuel cost. Understanding these different label systems helps when researching cars across international markets before importing.

Key Takeaways

  • Divide 235.215 by L/100km to get MPG (US gallons).
  • Lower L/100km means higher MPG — they are inversely related.
  • 6 L/100km ≈ 39 MPG is a useful midpoint benchmark.
  • European WLTP ratings tend to be 10-20% more optimistic than US EPA numbers.
  • For UK Imperial MPG, divide 282.481 by L/100km instead.
