Fuel consumption conversion is critical for international travelers and car buyers. The world is split: the US wants high numbers (MPG), while Europe wants low numbers (L/100km). To make it worse, the UK uses a different gallon than the US. A car that gets 30 MPG in the US gets about 36 MPG in the UK and uses 7.8 L/100km in France. Our converter bridges these gaps instantly. Key benchmarks: 30 US MPG ≈ 7.8 L/100km, and 50 US MPG ≈ 4.7 L/100km.
