About Fuel Efficiency Converter (km/l, l/100km, mpg)

The Fuel Efficiency Converter helps you convert between different fuel economy units such as kilometers per liter (km/l), liters per 100 kilometers (l/100 km), and miles per gallon (mpg). It’s perfect for comparing car mileage and fuel efficiency across different measurement systems.

Formula (Simple Explanation)

mpg = 235.215 / (l/100 km)   or  l/100 km = 235.215 / mpg

Fuel efficiency shows how far a vehicle can travel using a specific amount of fuel. The conversion factor 235.215 is based on the relationship between miles, kilometers, and liters.

Example:

Input: Convert 15 km/l to mpg

Output: 15 km/l ≈ 35.3 mpg (U.S.)

Steps to Use:

  1. Select the fuel efficiency unit you want to convert from (km/l, l/100 km, or mpg).
  2. Enter the vehicle’s efficiency value.
  3. Choose the target unit you want to convert to.
  4. Click 'Convert' to see your result instantly.

Frequently Asked Questions

What does km/l mean?

Km/l stands for kilometers per liter and shows how many kilometers a vehicle can travel using one liter of fuel. The higher the value, the better the fuel efficiency.

What is l/100 km?

Liters per 100 kilometers (l/100 km) measures how many liters of fuel are consumed to travel 100 kilometers. A lower value means better fuel economy.

What is mpg and how is it used?

Miles per gallon (mpg) measures how far a vehicle can travel using one gallon of fuel. It’s commonly used in the United States and the UK.

How do I convert between mpg and l/100 km?

Use the formula mpg = 235.215 / (l/100 km). For example, a car using 8 l/100 km has about 29.4 mpg efficiency.

Which unit should I use to compare cars internationally?

Use l/100 km for metric systems and mpg for imperial systems. Many global auto reviews now include both for easy comparison.
