To compute fuel consumption in kilometers per liter (km/l), use the following formula:
km/l = Distance traveled (km) ÷ Fuel used (liters)[1][3][8]
Here are the steps to calculate fuel consumption in km/l:
- Fill your fuel tank to full and reset your trip meter, or note your odometer reading.
- Drive as usual until your next refuel, ideally after a significant distance to get a more accurate average.
- At your next fill-up, record the number of liters it takes to refill the tank and the kilometers traveled (from the trip meter or difference in odometer readings).
- Use the formula: divide the distance traveled (in kilometers) by the amount of fuel used (in liters). The result is your fuel consumption in km/l.
Example: If you travel 150 kilometers and use 8 liters of fuel, your fuel consumption is:
150 ÷ 8 = 18.75 km/l[1]
This calculation helps you understand your vehicle’s fuel efficiency and compare it with standards or other vehicles. Many countries that use the metric system utilize the km/l metric for tracking fuel efficiency[1].
