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

Conversion Quick Reference

• 30 MPG (US) ≈ 7.84 L/100km ≈ 12.75 km/L

• 40 MPG (US) ≈ 5.88 L/100km ≈ 17.01 km/L

• 50 MPG (US) ≈ 4.70 L/100km ≈ 21.26 km/L

• 6 L/100km ≈ 39.2 MPG (US) ≈ 16.67 km/L

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.
