      "a": "km/L = mpg (UK) × 0.354006; the miles per imperial gallon (UK mpg)-to-kilometers per liter page applies it directly."

      "q": "Why is there no single multiplication factor?",
      "a": "Fuel-economy units are reciprocal (distance per volume versus volume per distance), so the conversion divides a constant by the value instead of multiplying."
