1. What is MPG to L/100km Conversion?

The MPG to L/100km conversion allows you to translate fuel efficiency measurements between the US (miles per gallon) and metric (liters per 100 kilometers) systems. This is particularly useful when comparing vehicle efficiency internationally.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( MPG \) — Miles per gallon (US measurement)
• \( L/100km \) — Liters per 100 kilometers (metric measurement)
• 235.215 — Conversion factor combining miles to km and gallons to liters

Explanation: The formula accounts for both distance and volume unit conversions between the US and metric systems.

3. Importance of Fuel Efficiency Conversion

Details: Understanding both MPG and L/100km measurements is essential for comparing vehicle efficiency internationally, calculating fuel costs for trips, and understanding environmental impact across different measurement systems.

4. Using the Calculator

Tips: Simply enter your vehicle's MPG rating to get the equivalent L/100km value. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is 235.215 the conversion factor?
A: It combines 1 mile = 1.609344 km and 1 US gallon = 3.785411784 liters (100 × 3.785411784 / 1.609344 ≈ 235.215).

Q2: How do I convert L/100km back to MPG?
A: Use the inverse formula: MPG = 235.215 / L/100km.

Q3: Which is better - higher MPG or lower L/100km?
A: Higher MPG indicates better efficiency, while lower L/100km indicates better efficiency (they're inversely related).

Q4: Are UK MPG and US MPG the same?
A: No, UK gallons are larger (4.54609 liters vs 3.78541 liters). This calculator uses US MPG.

Q5: What's a good L/100km value?
A: Typical values range from 5-12 L/100km for passenger vehicles. Lower is more efficient (e.g., 5 L/100km ≈ 47 MPG).
