Advanced Fuel Economy & Consumption Converter

Seamlessly convert between all major international fuel efficiency standards with our advanced calculator. This tool intelligently handles both fuel **economy** formats (like MPG, where higher is better) and fuel **consumption** formats (like L/100km, where lower is better), performing the complex inversion math for you automatically. It's an essential tool for travelers, automotive enthusiasts, and engineers.

How It Works

Our converter is designed for accuracy and ease of use, providing instant conversions between different measurement types.

  1. Enter a Value: Type your vehicle's fuel efficiency figure into the "From" field.
  2. Select Your Units: Choose your starting unit (e.g., Liters/100km) and your target unit (e.g., Miles/gallon US).
  3. Get Instant Conversion: The tool automatically performs the correct conversion, including the necessary inversion if switching between economy and consumption formats, and displays the result in the "To" field.

Key Features

  • Intelligent Dual-Format Conversion: The core strength of this tool is its ability to seamlessly convert between:
    • Fuel Economy units (distance per volume, like MPG or km/L).
    • Fuel Consumption units (volume per distance, like L/100km or gallons/100 miles).
  • Comprehensive Unit Library: Convert between dozens of units, including the most common international standards:
    • Miles per Gallon (US and UK)
    • Liters per 100 Kilometers (L/100km)
    • Kilometers per Liter (km/L)
    • Gallons per 100 Miles (US and UK)
  • Real-Time & Precise: All calculations update instantly as you type, using a high-precision engine to ensure accurate results.
  • Intuitive Interface: A clean, two-panel layout makes conversion straightforward and easy to understand.
  • Swap Functionality: Easily reverse the "From" and "To" units with a single click of the swap button.
  • Convenient Tools: Includes a one-click "Copy to Clipboard" button and a persistent Light/Dark mode for comfortable viewing.
