Kilometers Per Liter to Liters Per 100 Km
12 kilometers per liter equals 8.333 liters per 100 km. The two run in opposite directions, so a higher figure on one side is a lower figure on the other.
L/100km = 100 ÷ km/L

Understanding Fuel Economy Units
MPG (Miles per Gallon): Distance traveled per unit of fuel
L/100km: Fuel consumed per 100 kilometers (lower is better)
km/L: Distance per liter (higher is better)
US vs UK Gallons: US gallon = 3.785L, UK gallon = 4.546L
Inverse Relationship: Higher MPG = Lower L/100km
Global Standards: Most countries use L/100km
Fuel Efficiency Categories
Excellent: 40+ MPG (5.9 L/100km or less)
Good: 30-39 MPG (6.0-7.8 L/100km)
Average: 20-29 MPG (8.1-11.8 L/100km)
Below Average: 15-19 MPG (12.4-15.7 L/100km)
Poor: Under 15 MPG (over 15.7 L/100km)
Hybrid/Electric: 50+ MPG equivalent

About This Conversion
Kilometers per liter to liters per 100 km divides 100 by the km/L figure. Both are metric, but they run in opposite directions: km/L is distance per fuel, L/100km is fuel per distance.
Km/L is the standard figure in Japan, India and much of South America, while Europe uses L/100km, so this is the conversion for comparing a car sold in both. A 20 km/L rating is 5 L/100km, and the pleasing symmetry that 10 km/L is exactly 10 L/100km is the only point where the two scales cross.
Frequently Asked Questions
What is 12 km/L in L/100km?
12 km/L is 8.33 L/100km.
What is the formula?
L/100km = 100 ÷ km/L. The same formula converts back the other way.
Where is km/L used?
It is the standard fuel-economy figure in Japan, India, Brazil and several other markets.
Is there a value where both are the same?
Yes, 10. A car doing 10 km/L uses exactly 10 L/100km.
Worth Knowing
US Gallon vs Imperial Gallon
A US gallon is 3.785411784 litres and an imperial (UK) gallon is 4.54609 litres, making the imperial gallon about 20.1 percent larger.
