    About Fuel Efficiency Conversion

    Fuel efficiency measures how far a vehicle can travel per unit of fuel consumed. Different regions use different units, making conversion essential for international comparisons and automotive specifications.

    Fuel Efficiency Systems

    • US System: Miles per Gallon (MPG) - distance per fuel volume
    • Metric System: Liters per 100 km (L/100km) - fuel per distance
    • Alternative: Kilometers per Liter (km/L) - distance per fuel volume
    • UK System: Miles per Imperial Gallon (larger than US gallon)

    Efficiency vs Consumption

    Note that MPG and L/100km have an inverse relationship: higher MPG means better efficiency, while lower L/100km means better efficiency. This converter handles these inverse relationships automatically.

    Typical Vehicle Efficiency

    • Compact car: 30-40 MPG (6-8 L/100km)
    • Mid-size sedan: 25-35 MPG (7-9 L/100km)
    • SUV: 20-30 MPG (8-12 L/100km)
    • Hybrid vehicles: 40-60 MPG (4-6 L/100km)
