Fuel per Distance
Liters per 100 kilometers measures how much fuel a car uses to travel 100 km. Lower is better: 5 L/100km is efficient, 10 L/100km is thirsty. This is the inverse of MPG's logic, which trips people up.
Comparing Cars
Because L/100km measures fuel per distance, the differences are linear and intuitive: a car using 6 L/100km uses twice the fuel of one using 3 L/100km. With MPG, the same doubling is harder to see — see the inverse-conversion guide.
