1. What is MPG?

MPG (Miles Per Gallon) is a measurement of fuel efficiency in vehicles, showing how many miles a vehicle can travel using one gallon of fuel. It's the standard measurement for fuel economy in the United States.

2. How Does the Calculator Work?

The calculator uses the simple MPG formula:

Where:

• \( miles \) — Distance traveled in miles
• \( gallons \) — Fuel consumed in gallons

Explanation: The calculation divides the total miles driven by the total gallons of fuel used during that trip.

3. Importance of MPG Calculation

Details: Knowing your vehicle's MPG helps you understand fuel efficiency, estimate fuel costs for trips, compare vehicles, and identify potential mechanical issues if MPG drops suddenly.

4. Using the Calculator

Tips: For accurate results, reset your trip odometer when filling up, then note the miles driven and gallons used at your next fill-up. Enter both values (must be greater than zero).

5. Frequently Asked Questions (FAQ)

Q1: What's considered good MPG?
A: Generally, 25+ MPG is good for city driving, 30+ for highway. Hybrids/electric vehicles get significantly higher MPG equivalents.

Q2: How can I improve my MPG?
A: Regular maintenance, proper tire inflation, reducing excess weight, and avoiding aggressive driving can improve MPG.

Q3: Why does my MPG vary?
A: MPG varies based on driving conditions (city vs highway), speed, weather, vehicle load, and maintenance status.

Q4: How accurate is this calculation?
A: Accuracy depends on precise measurement of miles and gallons. For best results, track several fill-ups and average the MPG.

Q5: What's the difference between MPG and L/100km?
A: MPG is used in the US (higher is better), while liters per 100km (used elsewhere) measures fuel used per distance (lower is better).
