How to Calculate Fuel Consumption

Metric System (L/100km)

Fuel consumption = (Fuel used / Distance traveled) × 100

Imperial System (MPG)

Fuel consumption = Distance traveled / Fuel used

Trip Cost Calculation

Total cost = (Distance × Fuel consumption × Fuel price) / 100 (metric) or Total cost = (Distance / Fuel consumption) × Fuel price (imperial)
