Liters per kilometer (L/km) is a metric measurement of fuel consumption that indicates how many liters of fuel a vehicle consumes to travel one kilometer. It's commonly used to measure and compare fuel efficiency of vehicles.
The calculator uses the simple formula:
Where:
Explanation: This calculation provides the fuel consumption rate per kilometer traveled, which is useful for understanding vehicle efficiency and fuel costs.
Details: Calculating liters per kilometer helps vehicle owners monitor fuel consumption, compare efficiency between different vehicles, estimate fuel costs for trips, and identify changes in vehicle performance that may indicate maintenance needs.
Tips: Enter the total fuel consumed in liters and the distance traveled in kilometers. Both values must be positive numbers. For accurate results, measure fuel consumption over a significant distance (preferably a full tank).
Q1: What is a good L/km value?
A: Lower values indicate better fuel efficiency. Typical values range from 0.05-0.15 L/km for most passenger vehicles, with smaller, more efficient vehicles achieving lower values.
Q2: How does L/km compare to km/L?
A: L/km is the inverse of km/L. While L/km shows fuel consumed per distance, km/L shows distance traveled per liter of fuel. Both measure fuel efficiency but present it differently.
Q3: Why is my actual consumption different from manufacturer specifications?
A: Manufacturer tests are conducted under ideal conditions. Real-world consumption varies based on driving habits, traffic conditions, vehicle maintenance, load, and terrain.
Q4: How can I improve my vehicle's fuel efficiency?
A: Regular maintenance, proper tire inflation, smooth driving, reducing unnecessary weight, and avoiding excessive idling can improve fuel efficiency.
Q5: Should I calculate L/km over multiple trips for accuracy?
A: Yes, calculating over multiple trips or a full tank provides a more accurate average than single short trips, which can be affected by various factors.
