MPG = miles driven / gallons used.
Example
Use miles traveled and gallons used to determine real-world MPG after a trip.
When to Use
- Vehicle expense tracking
- Trip budgeting
- Fleet efficiency checks
Best Practices
- Validate units and assumptions before interpreting output.
- Compare at least two scenarios to avoid single-point bias.
- Use results as decision support, then cross-check critical outcomes.
