⚡ Pro Tips for Fuel Efficiency Conversions

1
Understand the Formats
MPG and km/L measure distance per fuel (higher is better). L/100km measures fuel per distance (lower is better).
2
US vs UK Gallons
US MPG and UK MPG are different! UK gallon is 20% larger. 30 US MPG ≈ 36 UK MPG.
3
Quick Estimates
To roughly convert L/100km to MPG: divide 235 by L/100km. For exact conversions, use our tool!
4
Real-World vs EPA
Manufacturer ratings are often optimistic. Real-world fuel economy is typically 10-20% lower.

🎓 Understanding Fuel Efficiency Units

Common Fuel Efficiency Units

  • MPG (US): Miles per gallon (US), distance traveled per US gallon of fuel
  • MPG (UK): Miles per gallon (Imperial), uses larger UK gallon
  • L/100km: Liters per 100 kilometers, fuel consumed per 100 km (metric standard)
  • km/L: Kilometers per liter, distance traveled per liter of fuel
  • MPG (Imperial): Same as UK MPG, used in UK and some Commonwealth countries

Typical Fuel Efficiency Values

  • Compact Car: 30-40 US MPG (5.9-7.8 L/100km)
  • Mid-Size Sedan: 25-35 US MPG (6.7-9.4 L/100km)
  • SUV: 20-28 US MPG (8.4-11.8 L/100km)
  • Hybrid: 45-55 US MPG (4.3-5.2 L/100km)
  • Electric (equivalent): 100+ MPGe (2.4 L/100km equivalent)
🚗 Real-World Example: Road Trip Planning

Situation: You're planning a 500-mile trip. Your car gets 32 MPG and gas costs $3.50/gallon.

Solution: 500 miles ÷ 32 MPG = 15.6 gallons needed. 15.6 × $3.50 = $54.60 total fuel cost!

❓ Frequently Asked Questions (FAQ)

How do I convert MPG to L/100km?
Divide 235.21 by MPG to get L/100km. For example: 235.21 ÷ 30 MPG = 7.84 L/100km. Note: Lower L/100km is better!
How do I convert L/100km to MPG?
Divide 235.21 by L/100km to get US MPG. For example: 235.21 ÷ 6 L/100km = 39.2 MPG.
What's the difference between US MPG and UK MPG?
UK (Imperial) gallon is 4.546 liters while US gallon is 3.785 liters. UK MPG values are about 20% higher than US MPG for the same vehicle. 30 US MPG = 36 UK MPG.
Why is lower L/100km better?
L/100km measures fuel consumed per distance. Lower numbers mean less fuel used, so it's more efficient. It's the opposite of MPG where higher is better.
Can I convert between any two units?
Yes! Our converter supports conversions between all available fuel efficiency units - US to metric, UK to US, or within the same system.
How accurate are the conversions?
Our conversions use standard conversion factors and are accurate to multiple decimal places. The precision is suitable for vehicle comparison and fuel cost calculations.
What's good fuel economy?
For gasoline cars: 30+ US MPG (under 8 L/100km) is good, 40+ MPG (under 6 L/100km) is excellent. Hybrids often achieve 45-55 MPG (4-5 L/100km).
Will this work on my phone?
Yes! The fuel efficiency converter is fully responsive and works perfectly on smartphones and tablets. All features are available on mobile devices.
How do I calculate fuel cost for a trip?
Divide trip distance by your MPG to get gallons needed, then multiply by fuel price per gallon. Example: 300 miles ÷ 30 MPG = 10 gallons × $3.50 = $35.
Can I use this for diesel vehicles?
Yes! The converter works for any fuel type - gasoline, diesel, or alternative fuels. The units measure volume efficiency regardless of fuel type.
