Formula used
Core efficiency
- L/100km = (Fuel_L ÷ Distance_km) × 100
- km/L = Distance_km ÷ Fuel_L
- MPG(US) = Miles ÷ US_Gallons
- MPG(UK) = Miles ÷ UK_Gallons
Conversions & costs
- km = miles × 1.609344
- L = US_gal × 3.785411784
- L = UK_gal × 4.54609
- Cost_total = Fuel_L × Price_per_L
- Cost/100km = (Cost_total ÷ Distance_km) × 100
Tip: Use consistent fill method (full-to-full) to reduce noise.
