Example: 7 L/100km → 100 ÷ 7 = 14.29 km/L
L/100km and km/L measure the same thing from opposite ends of the fraction. Litres per 100 km asks “how much fuel for a fixed journey?”; kilometres per litre asks “how far on a fixed amount of fuel?” The conversion is its own inverse: km/L = 100 ÷ L/100km, and L/100km = 100 ÷ km/L.
This self-inverse property means one formula handles both directions. A car at 7 L/100km travels 14.3 km on each litre. At 5 L/100km, a single litre takes you 20 km. The relationship is hyperbolic, not linear: halving L/100km doubles km/L, but equal spacing on one scale produces unequal spacing on the other.
km/L is the standard fuel economy unit in Japan, India, South Korea, and several other Asian markets. L/100km dominates Europe, Australia, and South Africa. The United States uses mpg exclusively. All three scales measure exactly the same physical efficiency.
km/L = 100 ÷ L/100km. For example, 7 L/100km = 100 ÷ 7 = 14.29 km/L.
Japan, India, South Korea, the Philippines, Thailand, and several other Asian countries use km/L as the primary fuel economy unit. L/100km dominates Europe and Australia.
Yes, it is mathematically exact: km/L = 100 ÷ L/100km. Any rounding in the table above is display-only.
