About Fuel Efficiency Conversion
Different regions use different standards to measure fuel efficiency. The UK and US use MPG (miles per gallon), while Europe uses L/100km (litres per 100 kilometres).
MPG (Miles Per Gallon): Higher numbers mean better efficiency. This shows how many miles you can travel with one gallon of fuel.
L/100km (Litres per 100km): Lower numbers mean better efficiency. This shows how many litres of fuel you need to travel 100 kilometres.
Frequently Asked Questions
What is Resolvo?
Resolvo is a UK-based platform that helps drivers appeal unfair parking tickets and PCNs. We provide free tools like this fuel efficiency converter alongside our expert parking ticket appeal services, helping you save money on both fuel costs and unjust parking fines.
What's the difference between MPG and L/100km?
MPG (miles per gallon) shows how many miles you can travel with one gallon of fuel - higher is better. L/100km shows how many litres you need for 100 kilometres - lower is better.
How do you convert MPG to L/100km?
Divide 282.481 by the MPG value. For example, 35 MPG = 282.481 ÷ 35 = 8.1 L/100km. Our converter does this calculation automatically.
Which measurement is better?
Neither is inherently better - they're just different ways of expressing the same thing. MPG is used in UK/US, while L/100km is used in Europe and most other countries.
Why do I need to convert between them?
When comparing cars from different markets, reading international reviews, or understanding fuel efficiency in different formats. It's also useful when travelling abroad.
Is the conversion accurate?
Yes, this converter uses the standard conversion factor (282.481) and provides accurate results. The formula is internationally recognised and precise.
What's considered good fuel efficiency?
In MPG: 30+ is average, 40+ is good, 50+ is excellent. In L/100km: 9+ is average, 7 or less is good, 5 or less is excellent. Lower L/100km = higher MPG.
Do different gallon sizes affect conversion?
Yes, this converter uses UK imperial gallons. US gallons are smaller, so US MPG figures appear higher than UK MPG for the same efficiency level.
Can I use this for any vehicle type?
Yes, the conversion works for cars, motorcycles, vans, trucks, or any vehicle. The mathematical relationship between MPG and L/100km remains constant.
How does this help with parking tickets?
While fuel efficiency doesn't directly relate to parking, Resolvo helps you save money on both fuel tracking and appealing unfair parking fines.
Should I track my fuel efficiency?
Yes, regular monitoring helps you detect engine problems, optimize driving habits, compare vehicles, and manage fuel costs effectively.
How do I convert UK MPG to European fuel consumption?
Divide 282.481 by your UK MPG figure. For example: 35 UK MPG = 282.481 ÷ 35 = 8.1 L/100km. This is the standard European fuel consumption rating.
What does L/100km mean?
Litres per 100 kilometres shows how many litres of fuel your car needs to travel 100km. Lower numbers are better - a fuel-efficient car might use 5-6 L/100km, while a large SUV might use 10+ L/100km.
Why do European cars show different fuel figures?
European manufacturers quote L/100km (lower is better), while UK/US use MPG (higher is better). They measure the same thing differently - always convert to compare accurately.
How do I compare fuel efficiency internationally?
Convert all figures to the same unit (either MPG or L/100km) using our converter. This is essential when comparing cars from different markets or reading international reviews.
What is WLTP fuel consumption?
WLTP (Worldwide Harmonized Light Vehicles Test Procedure) is the current EU standard for measuring fuel consumption in L/100km. It's more realistic than older NEDC figures but still differs from real-world driving.
