Question 1

How do I calculate fuel cost for a trip?

Accepted Answer

To calculate fuel cost, divide the trip distance by your vehicle's MPG to find gallons needed, then multiply by the fuel price per gallon. Formula: (Distance ÷ MPG) × Price = Cost.

Question 2

How do I switch between Miles and Kilometers?

Accepted Answer

Use the 'Distance Unit' dropdown at the top of the form to toggle between Miles and Kilometers. The calculator automatically adjusts efficiency labels and conversions.

Question 3

What's the difference between MPG and L/100km?

Accepted Answer

MPG (Miles Per Gallon) is used in the US - higher is better. L/100km (Liters per 100 Kilometers) is used in metric countries - lower is better. Our calculator handles both automatically.
