How do I estimate gas cost for a trip?

Cost = (Distance / MPG) × Price per gallon. For 300 miles at 25 MPG and $3.50/gal: (300/25) × 3.50 = $42.

How do I convert MPG to L/100km?

L/100km = 235.215 / MPG. So 30 MPG = 7.84 L/100km. Lower L/100km is more efficient.

Speed (optimal 45-65 mph), AC use, tire pressure, weight, driving style, and terrain all impact MPG significantly.
