Assumptions and estimates

  • MPG conversions distinguish the Imperial gallon (4.54609 L) from the US gallon (3.785411784 L). Distance is one-way as entered; add return travel separately. Parking, tolls and vehicle wear are excluded.
  • Method: Litres = distance × L/100km ÷ 100. MPG first converts using the selected gallon definition.
  • Fuel only: tolls, parking, maintenance and vehicle depreciation are excluded.
