Km/L Formula:
| From: | To: |
Km per litre (km/L) is a measurement of fuel efficiency that indicates how many kilometres a vehicle can travel on one litre of fuel. It's a standard metric used in Australia and many other countries to compare vehicle fuel consumption.
The calculator uses the simple formula:
Where:
Explanation: This calculation provides the average fuel efficiency over the measured distance, giving you the number of kilometres your vehicle can travel per litre of fuel.
Details: Calculating km/L helps vehicle owners monitor fuel consumption, identify changes in efficiency, compare different vehicles, and estimate fuel costs for trips. It's essential for budgeting and environmental awareness.
Tips: Enter the total distance traveled in kilometres and the total fuel consumed in litres. For accurate results, reset your trip meter when refuelling and record the exact amount of fuel added.
Q1: What is a good km/L rating in Australia?
A: Fuel efficiency varies by vehicle type. Small cars typically achieve 15-20 km/L, while larger vehicles may get 8-12 km/L. Electric and hybrid vehicles can achieve much higher equivalent ratings.
Q2: How can I improve my vehicle's km/L?
A: Regular maintenance, proper tyre inflation, smooth driving, reducing unnecessary weight, and avoiding excessive idling can all improve fuel efficiency.
Q3: Should I calculate km/L over multiple tanks?
A: Yes, calculating over several fuel tanks provides a more accurate average as driving conditions and fuel quality can vary between fill-ups.
Q4: How does km/L compare to L/100km?
A: km/L and L/100km are inversely related. To convert km/L to L/100km, divide 100 by the km/L value (e.g., 10 km/L = 10 L/100km).
Q5: Does driving style affect km/L significantly?
A: Yes, aggressive acceleration, high speeds, and frequent braking can reduce fuel efficiency by 15-30% compared to smooth, economical driving.
