How do I convert mpg US to L/100km?

You can use the `convert_efficiency` tool by providing the value and setting the source unit to `mpg_us`.

Can I calculate the cost of a long road trip?

Yes, use the `calculate_trip_cost` tool with your trip distance, fuel price, and vehicle efficiency.

What happens if I enter an unrealistic efficiency value?

The `validate_efficiency_range` tool will flag values below 1 mpg or above 200 mpg as unrealistic.
