1. What is the Road Gas Calculation?

The Road Gas calculation estimates the total fuel cost for a trip based on distance, vehicle fuel efficiency, and current gas prices. It helps travelers budget for their journey.

2. How Does the Calculator Work?

The calculator uses the Road Gas formula:

Where:

• Total Miles — Distance of your trip in miles
• MPG — Your vehicle's miles per gallon rating
• Cost per Gallon — Current price of gasoline in USD

Explanation: The equation calculates gallons needed by dividing miles by MPG, then multiplies by cost per gallon to get total fuel cost.

3. Importance of Road Trip Planning

Details: Accurate fuel cost estimation helps with budgeting, comparing different routes, and choosing the most economical vehicle for long trips.

4. Using the Calculator

Tips: Enter total trip distance in miles, your vehicle's MPG rating, and current local gas price per gallon. All values must be positive numbers.
