- Enter total planned trip distance.
- Input vehicle fuel consumption rating and current fuel price per unit.

Technical Specifications & How It Works
In metric mode, total liters required equals (Distance / 100) × L/100km. In imperial mode, gallons required equals Distance / MPG.
The tool automatically converts fuel ratings between US MPG and European L/100km (MPG = 235.215 / L/100km).
