How to Convert MPG to L/100km for International Car Shopping

Miles per gallon (MPG) is the fuel economy standard in the US and UK, while liters per 100 kilometers (L/100km) is used throughout Europe, Australia, and most other countries. When importing a vehicle or comparing models across markets, this conversion is essential. The formula uses the constant 235.215, which accounts for the relationship between miles, gallons, liters, and kilometers.

  1. Take the fuel economy value in miles per gallon (MPG).
  2. Divide 235.215 by the MPG value.
  3. The result is the fuel consumption in liters per 100 kilometers.
  4. Remember: higher MPG means lower L/100km (they are inversely related).
💡 Tip: A quick mental check: 30 MPG ≈ 7.8 L/100km, and 40 MPG ≈ 5.9 L/100km. If your result is between 4 and 15, you are likely in the right range for a passenger car.

Solved Examples: MPG to L/100km

Question 1: A Ford F-150 gets 22 MPG on the highway. What is that in L/100km?

Solution:

L/100km = 235.215 ÷ MPG

= 235.215 ÷ 22

= 10.69 L/100km

Answer: 22 MPG = 10.69 L/100km — typical for a full-size pickup truck.

Question 2: A Toyota Camry is rated at 34 MPG combined. Convert to L/100km.

Solution:

L/100km = 235.215 ÷ MPG

= 235.215 ÷ 34

= 6.92 L/100km

Answer: 34 MPG = 6.92 L/100km — competitive with European mid-size sedans.

Question 3: A Prius achieves 56 MPG in city driving. Express in L/100km.

Solution:

L/100km = 235.215 ÷ MPG

= 235.215 ÷ 56

= 4.20 L/100km

Answer: 56 MPG = 4.20 L/100km — excellent efficiency even by European standards.

  3. Convert 45 MPG to L/100km. (Answer: 5.23 L/100km)
  4. A sports car manages 18 MPG. Express in L/100km. (Answer: 13.07 L/100km)
  5. Convert 65 MPG to L/100km. (Answer: 3.62 L/100km)

Why the Relationship Is Inverse, Not Linear

MPG measures distance per unit of fuel (higher is better), while L/100km measures fuel per unit of distance (lower is better). This inverse relationship means the conversion uses division rather than multiplication. It also means improvements are not proportional: going from 10 to 20 MPG saves far more fuel than going from 40 to 50 MPG. This is why Europeans prefer L/100km — the savings scale linearly with the number.

Imperial vs. US Gallons: Watch the Difference

UK fuel economy uses Imperial gallons (4.546 liters), while US MPG uses US gallons (3.785 liters). The conversion constant 235.215 is for US gallons. For Imperial MPG, use 282.481 instead. A car rated 40 MPG in the UK would be about 33.3 MPG in US terms. Always check which gallon standard the manufacturer used before converting.

Key Takeaways

  • Divide 235.215 by MPG to get L/100km (US gallons).
  • The relationship is inverse: higher MPG = lower L/100km.
  • For Imperial (UK) gallons, use 282.481 instead of 235.215.
  • 30 MPG ≈ 7.84 L/100km is a useful benchmark for average cars.
  • L/100km is preferred internationally because fuel savings scale linearly.
