What is km/L and how does it relate to L/100km?

km/L measures how many kilometers you can travel per liter. Divide 100 by km/L to get L/100km.

Why do different countries use different fuel consumption units?

L/100km is used throughout Europe and Canada, MPG in the US and UK, and km/L in parts of Asia and Africa.

Is higher or lower L/100km better?

Lower L/100km is better, it means the vehicle uses less fuel to travel the same distance.

Is higher or lower MPG better?

Higher MPG is better, it means the vehicle travels further on the same amount of fuel.

What is the average fuel consumption for a car?

The average modern car consumes about 6-8 L/100km (30-40 MPG), depending on size and engine.

Can I convert fuel consumption for electric vehicles?

EV efficiency is usually measured in kWh/100km rather than fuel consumption, as EVs don't consume liquid fuel.

How accurate are the fuel consumption conversions?

Conversions use exact mathematical formulas based on the US gallon (3.785411784 L) and UK gallon (4.54609 L).
