We built the FreeWWW Fuel Economy Converter because vehicle efficiency is expressed differently around the world, making international car comparisons and trip-cost planning unnecessarily confusing. The project started as a simple MPG and L/100km converter. We expanded it to support US and UK MPG, kilometers per liter, efficiency ratings, multiple currencies, fuel-price units, and trip-cost estimates. We then added side-by-side vehicle comparisons and a locally stored fill-up log for tracking real-world mileage, fuel usage, spending, and long-term averages. Our goal is to give drivers, travelers, and car shoppers one practical place to understand fuel efficiency and operating costs. Which vehicle-planning feature should we add next?
