Frequently Asked Questions
What's the difference between US MPG and Imperial (UK) MPG, and why does it matter?
US MPG uses US gallons (3.785 liters) while Imperial MPG uses Imperial gallons (4.546 liters). This means the same vehicle will show about 20% higher efficiency numbers in Imperial MPG compared to US MPG. For example, 30 US MPG equals approximately 36 Imperial MPG. This distinction is crucial when comparing vehicles or fuel efficiency ratings from different countries.
Why do L/100km and MPG scales work in opposite directions for fuel efficiency?
MPG measures how far you can travel per unit of fuel (higher = better efficiency), while L/100km measures how much fuel you consume per distance (lower = better efficiency). This is why a fuel-efficient car might get 40 MPG or 5.9 L/100km - both represent good efficiency, but the scales are inverted. Our converter helps you understand both perspectives and provides efficiency analysis.
How accurate are the conversions for professional automotive applications?
Our converter uses official conversion factors with high precision: 235.214583 for US MPG to L/100km and 282.481053 for Imperial MPG conversions. These factors are based on exact gallon-to-liter ratios and are suitable for professional automotive work, regulatory compliance, fleet management, and technical documentation requiring precise fuel efficiency conversions.
Can I use this converter for comparing EPA ratings with European fuel economy labels?
Yes! The converter handles the fundamental unit conversions between US EPA ratings (MPG) and European fuel economy labels (L/100km). However, keep in mind that EPA and EU testing procedures may differ slightly, so while the unit conversion is precise, actual real-world efficiency may vary due to different testing standards and driving cycle methodologies.
What fuel efficiency values are considered good, average, or poor for different vehicle types?
Generally: compact cars achieving 30+ MPG (7.8 L/100km) are good, mid-size cars getting 25-30 MPG (9.4-7.8 L/100km) are average, and SUVs/trucks with 20-25 MPG (11.8-9.4 L/100km) are typical. However, standards vary by vehicle class, year, and region. Our converter provides efficiency context to help interpret whether converted values represent good or poor fuel economy for your specific application.
