How This Tool Works
Our Fuel Efficiency Converter tool makes it easy to convert between different fuel efficiency measurements:
- Enter the value you want to convert in the input field
- Select the unit you are converting from (MPG or L/100km)
- Select the unit you want to convert to
- Click the "Convert" button to see the result
- Use the "Swap Units" button to quickly switch between units
- Copy the result to your clipboard by clicking the copy button
The converter uses the following formulas:
- MPG to L/100km: L/100km = 235.215 / MPG
- L/100km to MPG: MPG = 235.215 / L/100km
This converter is useful for:
- Comparing vehicle fuel efficiency across different regions
- Understanding fuel consumption in different measurement systems
- Calculating fuel costs for trips in different countries
- Environmental impact assessments
Frequently Asked Questions
What's the difference between MPG and L/100km?
MPG (Miles per Gallon) and L/100km (Liters per 100 Kilometers) are two different ways to measure fuel efficiency:
- MPG - Measures how many miles a vehicle can travel on one gallon of fuel. Higher MPG means better fuel efficiency.
- L/100km - Measures how many liters of fuel a vehicle uses to travel 100 kilometers. Lower L/100km means better fuel efficiency.
The key difference is that MPG is a distance per unit of fuel (higher is better), while L/100km is fuel per unit of distance (lower is better).
MPG is primarily used in the United States, while L/100km is used in most other countries, including Canada, Australia, and European nations.
How accurate is this fuel efficiency converter?
This converter performs precise mathematical conversions between MPG and L/100km using the standard conversion formulas:
- MPG to L/100km: L/100km = 235.215 / MPG
- L/100km to MPG: MPG = 235.215 / L/100km
The results are accurate to multiple decimal places, with the display precision adjusted for readability.
It's important to note that real-world fuel efficiency may vary based on driving conditions, vehicle maintenance, and other factors.
What is considered good fuel efficiency?
What constitutes "good" fuel efficiency depends on the type of vehicle:
- Small cars: 30+ MPG (7.8 L/100km or less) is considered good
- SUVs and trucks: 20+ MPG (11.8 L/100km or less) is considered good
- Hybrid vehicles: 40+ MPG (5.9 L/100km or less) is common
- Electric vehicles: Equivalent to 100+ MPG (2.4 L/100km or less)
It's worth noting that fuel efficiency standards have improved significantly over time, and what was considered good a decade ago might be below average today.
Why do different countries use different fuel efficiency measurements?
The difference in fuel efficiency measurements is primarily due to historical reasons and the adoption of different measurement systems:
- The United States primarily uses the imperial system (miles, gallons) and therefore uses MPG
- Most other countries use the metric system (kilometers, liters) and therefore use L/100km
- Some countries, like the UK, use a hybrid approach with metric fuel measurements (liters) but distance in miles, resulting in MPG (imperial)
The L/100km measurement is generally considered more intuitive for consumers as it directly shows fuel consumption per distance traveled, making it easier to calculate fuel costs for a trip.
