Fuel economy is measured two different ways around the world: distance per fuel (miles per gallon in the US and UK, kilometers per liter in Asia) or fuel per distance (liters per 100 km in Europe). These scales are inversely related, so converting between them requires a reciprocal formula, not simple multiplication. Note also that US and UK miles-per-gallon figures use different gallons.
