1. What is MPG?

MPG (Miles Per Gallon) is a measurement of fuel efficiency that shows how many miles a vehicle can travel using one gallon of fuel. It helps compare the fuel economy of different vehicles.

2. How Does the Calculator Work?

The calculator uses the MPG formula:

Where:

• \( Miles \) — Distance traveled in miles
• \( Litres \) — Fuel consumed in litres
• \( 3.78541 \) — Conversion factor (litres to gallons)

Explanation: The formula converts litres to gallons (since 1 gallon = 3.78541 litres) and then calculates how many miles were traveled per gallon of fuel.

3. Importance of MPG Calculation

Details: Knowing your vehicle's MPG helps estimate fuel costs, compare vehicle efficiency, and track changes in fuel economy that might indicate maintenance issues.

4. Using the Calculator

Tips: Enter the distance traveled in miles and the amount of fuel used in litres. For accurate results, reset your trip meter when filling up and record the litres added at the next fill-up.

5. Frequently Asked Questions (FAQ)

Q1: Why convert from litres to gallons?
A: MPG is traditionally measured in gallons (US standard), while fuel is often sold in litres, requiring this conversion.

Q2: What's a good MPG value?
A: Average MPG varies by vehicle type. Compact cars typically get 30-40 MPG, while SUVs might get 20-30 MPG. Higher values indicate better fuel efficiency.

Q3: How can I improve my MPG?
A: Regular maintenance, proper tire inflation, reduced idling, and smooth driving can all help improve fuel efficiency.

Q4: Is MPG the same as fuel consumption rate?
A: They're related but different. MPG measures distance per unit of fuel, while fuel consumption rate (L/100km) measures fuel per unit distance.

Q5: Why does my calculated MPG differ from the manufacturer's rating?
A: Manufacturer ratings are based on controlled tests. Real-world factors like driving style, traffic, and load affect actual MPG.
