1. What is MPG and L/km?

MPG (miles per gallon) and L/km (liters per kilometer) are both measurements of a vehicle's fuel efficiency. MPG is commonly used in the United States, while L/km is more common in metric system countries.

2. How Does the Conversion Work?

The conversion formula is:

Where:

• 235.215 — Conversion factor accounting for miles vs. km and gallons vs. liters
• L/km — Liters of fuel consumed per kilometer traveled

Explanation: This formula converts between the metric system (L/km) and imperial system (MPG) measurements of fuel efficiency.

3. Importance of Fuel Efficiency

Details: Understanding fuel efficiency helps compare vehicles, estimate fuel costs, and make environmentally conscious transportation choices.

4. Using the Calculator

Tips: Enter fuel consumption in L/km (must be greater than 0). The calculator will instantly show the equivalent MPG value.

5. Frequently Asked Questions (FAQ)

Q1: Why is 235.215 the conversion factor?
A: It accounts for 1 mile = 1.60934 km and 1 gallon = 3.78541 liters (100 / (1.60934 * 3.78541) ≈ 235.215).

Q2: What is a good MPG value?
A: Typically, 25-30 MPG is good for city driving, while 30-40 MPG is good for highway driving. Hybrid/electric vehicles can exceed 50 MPG.

Q3: How can I improve my vehicle's MPG?
A: Regular maintenance, proper tire inflation, reduced weight, and efficient driving habits can improve fuel efficiency.

Q4: Are there different types of MPG measurements?
A: Yes, there's US MPG (3.785L/gallon) and Imperial MPG (4.546L/gallon). This calculator uses US MPG.

Q5: Why do some countries use L/100km instead?
A: L/100km shows fuel consumption rather than efficiency, making it easier to calculate fuel costs for specific distances.
