1. What is Fuel Consumption?

Fuel consumption measures how much fuel a vehicle uses to travel a certain distance, typically expressed in liters per 100 kilometers (L/100km). It's a key metric for comparing vehicle efficiency and estimating fuel costs.

2. How Does the Calculator Work?

The calculator uses the fuel consumption formula:

\[ \text{Consumption (L/100km)} = \frac{\text{Fuel Used (L)}}{\text{Distance (km)}} \times 100 \]

Where:

Explanation: The formula converts the fuel-to-distance ratio to a standardized measure per 100 km for easier comparison between vehicles.

3. Importance of Fuel Consumption Calculation

Details: Knowing your vehicle's fuel consumption helps with budgeting fuel costs, comparing vehicle efficiency, and identifying potential mechanical issues when consumption changes unexpectedly.

4. Using the Calculator

Tips: For accurate results, measure fuel used between full tank fill-ups and record the exact distance traveled between fill-ups. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's considered good fuel consumption?
A: For passenger cars, 5-8 L/100km is excellent, 8-12 is average, and above 12 is poor. This varies by vehicle type and size.

Q2: How can I improve my fuel consumption?
A: Maintain proper tire pressure, avoid aggressive driving, reduce excess weight, and keep up with regular vehicle maintenance.

Q3: Why measure per 100km instead of km per liter?
A: L/100km provides a linear scale where halving the number doubles efficiency, making comparisons more intuitive.

Q4: Does fuel consumption vary with driving conditions?
A: Yes, city driving typically uses more fuel than highway driving due to frequent stops and starts.

Q5: How accurate is this calculation?
A: Accuracy depends on precise measurement of fuel used and distance. For best results, average over several fill-ups.
