Fuel Economy Converter: Convert Between MPG, L/100km, km/L, and More

Introduction

Fuel economy is critical for drivers worldwide, but different countries use different systems. Our fuel economy converter bridges these systems.

Conversion Formulas and Factors

The key formulas:

L/100km to MPG (US): MPG = 235.215 / (L/100km) MPG (US) to L/100km: L/100km = 235.215 / MPG L/100km to MPG (UK): MPG = 282.481 / (L/100km) km/L to L/100km: L/100km = 100 / (km/L)

Note: US gallon = 3.785 L, UK gallon = 4.546 L.

How to Use the Converter

Our fuel economy converter supports all common units. For example, 8 L/100km = 29.40 MPG (US).

Real-World Examples

Car Shopping: A European car does 5.5 L/100km, which is 42.77 MPG. Road Trip: Your US car shows 25 MPG, which is 9.41 L/100km. Fleet Management: A truck averages 12 L/100km = 23.54 MPG (UK).

Common Applications

• Car Buying: Comparing fuel efficiency across measurement systems
• International Travel: Estimating fuel costs abroad
• Fleet Management: Standardizing reporting across international fleets
• Environmental Calculations: Computing carbon emissions

Tips for Accurate Conversions

1. 1. Always specify US or UK gallons � 20% difference
2. 2. Lower L/100km = better fuel economy; higher MPG = better fuel economy
3. 3. Fuel economy is inversely proportional

Conclusion

Fuel economy conversions help compare vehicle efficiency across measurement systems. Our fuel economy converter supports both US and UK standards. For more tools, see the complete guide to unit converters.
