Example: 14 km/L → 100 ÷ 14 = 7.1 L/100km
Kilometres per litre is the fuel economy standard across Japan, South Korea, India, and much of Asia, while L/100km is the European and Australian standard. Both describe the same efficiency with a simple 100-divide relationship: L/100km = 100 ÷ km/L.
Because the formula is a reciprocal, the conversion is non-linear. A car improving from 10 to 12 km/L (a 20% efficiency gain) saves 1.67 L per 100 km. The same 20% gain from 15 to 18 km/L saves only 1.11 L per 100 km. This diminishing return is inherent to fuel consumption calculations.
When importing vehicle specifications from Japanese manufacturers or reading Indian automotive reviews, km/L figures are common. Converting to L/100km makes comparisons straightforward against European WLTP or Australian ADR test results.
L/100km = 100 ÷ 14 = 7.1 L/100km.
15 km/L = 100 ÷ 15 = 6.67 L/100km — a fairly efficient car by European standards.
Division produces a hyperbola, not a line. Equal km/L steps produce progressively smaller L/100km savings as efficiency increases.
