Fuel Efficiency Formula:
| From: | To: |
Fuel efficiency calculation measures how much fuel a vehicle consumes to travel a certain distance. In South Africa, fuel efficiency is typically measured in liters per 100 kilometers (L/100km), which indicates how many liters of fuel are needed to travel 100 kilometers.
The calculator uses the fuel efficiency formula:
Where:
Explanation: The formula calculates fuel consumption per 100 kilometers, providing a standardized measure for comparing vehicle efficiency.
Details: Monitoring fuel efficiency helps vehicle owners track fuel consumption patterns, identify potential vehicle issues, and optimize driving habits to reduce fuel costs and environmental impact.
Tips: Enter the total fuel used in liters and the distance traveled in kilometers. Both values must be positive numbers for accurate calculation.
Q1: What is a good fuel efficiency rating?
A: Good fuel efficiency varies by vehicle type. Generally, lower L/100km values indicate better efficiency. Most modern cars range from 5-12 L/100km.
Q2: How can I improve my vehicle's fuel efficiency?
A: Regular maintenance, proper tire inflation, smooth acceleration/braking, and reducing vehicle weight can improve fuel efficiency.
Q3: Why measure in L/100km instead of km/L?
A: L/100km is the standard measurement in South Africa and most countries as it provides a linear scale that's easier to compare across different vehicles.
Q4: Does driving conditions affect fuel efficiency?
A: Yes, city driving with frequent stops typically consumes more fuel than highway driving. Weather conditions and vehicle load also affect efficiency.
Q5: How accurate is this calculation?
A: The calculation is mathematically accurate based on the inputs provided. For best results, measure fuel consumption over multiple fill-ups and longer distances.
