Quick Answer

Formula: km/L = 100 ÷ L/100km

Reverse: Reverse: L/100km = 100 ÷ km/L

Example (average car): 8 L/100km = 12.5 km/L

⚠ L/100km is inverse — lower = better fuel economy, higher = worse.

Mental Math Tricks

km/L = 100 ÷ L/100km

This is an inverse relationship — NOT multiplication!

Key anchors

5 L/100km = 20 km/L. 8 L/100km = 12.5 km/L. 10 L/100km = 10 km/L. 15 L/100km = 6.67 km/L.

Warning

A lower L/100km means better fuel economy — opposite to km/L.

Automotive Journalist

Converts between regional fuel economy standards when reviewing international vehicle launches.

Traveller Renting Abroad

Converts fuel economy specs of rental vehicles between familiar and local units.

Environmental Analyst

Converts fuel efficiency data to calculate CO₂ emissions across vehicle fleets in different units.

Automotive Engineer

Validates fuel efficiency test results across EPA (MPG US), WLTP (L/100km), and JC08 (km/L) cycles.

Frequently Asked Questions

About L/100km and km/L

L/100km

Liters per 100 kilometers (L/100km) is the standard fuel consumption unit in most of Europe, Australia, Canada, China, and many other countries. Unlike other units, a LOWER L/100km value means BETTER fuel economy — it measures consumption, not efficiency.

EU emissions regulations are linked to L/100km figures. A typical European compact car achieves 5–7 L/100km; an efficient diesel 4–5 L/100km; a large SUV 9–12 L/100km. The EU 2025 fleet-average CO₂ target (95 g/km) corresponds roughly to 4.1 L/100km for petrol.

Interesting fact: L/100km and km/L are mathematically inverse: L/100km = 100 ÷ km/L. This means improvements aren't linear — going from 20 to 10 L/100km doubles efficiency, but going from 10 to 5 L/100km doubles it again. Small improvements at high consumption have disproportionately large real-world impact.

km/L

Kilometers per liter (km/L) is the fuel efficiency unit standard in Japan, South Korea, India, and many other Asian and Latin American countries. A higher km/L value means better fuel economy — the vehicle travels further on the same amount of fuel.

Japanese automakers publish km/L ratings from the JC08 or WLTC test cycles. A fuel-efficient city car in Japan might achieve 25–35 km/L; a typical sedan 15–20 km/L; a large SUV 8–12 km/L. The 2024 Toyota Prius achieves ~32 km/L under JC08 testing.

Interesting fact: The world record for fuel efficiency in a production vehicle is held by the Volkswagen XL1 (2013), which achieved approximately 111 km/L (261 mpg US) under NEDC testing — a two-seater diesel-electric hybrid that weighed only 795 kg.

About L/100km to km/L Conversion

Fuel efficiency is measured differently across regions: km/L (Japan, India), L/100km (Europe, Australia, Canada), MPG US (USA), MPG UK (Britain). Converting between them is essential for international vehicle comparisons. Note: L/100km uses an inverse relationship — lower = better, and you cannot simply multiply to convert.

Formula: km/L = 100 ÷ L/100km. Reverse: L/100km = 100 ÷ km/L.

All conversions use exact gallon definitions: US gallon = 3.785411784 L; Imperial gallon = 4.54609 L.
