Fuel Efficiency Formula:
From: | To: |
Litres per 100 kilometers (L/100km) is a metric measurement of fuel consumption that represents the amount of fuel (in litres) a vehicle consumes to travel 100 kilometers. This is the standard fuel efficiency measurement used in most countries outside of North America.
The calculator uses the standard formula:
Where:
Explanation: This calculation provides the average fuel consumption rate, making it easy to compare the fuel efficiency of different vehicles or driving conditions.
Details: Monitoring fuel efficiency helps vehicle owners understand their vehicle's performance, identify maintenance issues, and calculate fuel costs for trips. Lower L/100km values indicate better fuel efficiency.
Tips: For accurate results, measure fuel consumption over a significant distance (at least 100km is recommended). Record the exact amount of fuel added to the tank and the distance traveled since the last fill-up.
Q1: What is considered good fuel efficiency?
A: Generally, 5-8 L/100km is excellent for most cars, 8-12 L/100km is average, and above 12 L/100km is considered high consumption.
Q2: 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.
Q3: How does L/100km compare to MPG?
A: L/100km and MPG (miles per gallon) are inversely related. Lower L/100km values correspond to higher MPG values. You can convert between them using conversion formulas.
Q4: Why measure over 100km instead of per km?
A: The 100km standard provides more meaningful numbers that are easier to compare and work with for typical driving distances.
Q5: Does fuel efficiency vary with driving conditions?
A: Yes, fuel efficiency is affected by driving style, traffic conditions, terrain, vehicle load, weather, and maintenance status.
