This calculator requires the use of Javascript enabled and capable browsers. It is to determine the fuel (what ever it is) consumption of a vehicle, based on kilometers driven and liters, Imperial gallons or US gallons of fuel used, and optionally, the direct fuel expense per kilometer. (You may substitute either liters, Imperial gallons or US Gallons consistently in this calculator. You may also substitute Euros or dollars as long as it is consistent throughout.) All entries should be numeric. The current odometer reading MUST be greater than the previous odometer reading. The calculator assumes that the tank was full when you recorded the Previous Odometer reading. If you know the exact number of kilometers since the last fill, you can enter it direct in the Trip Odometer field instead of Current and Previous data entries. The cost per liter, Imperial gallon or US gallon is the pump price you pay, in Euros or dollars, for that quantity of fuel. The answer is returned as a number of kilometers per liter, Imperial gallon or US gallon, liters or gallons per 100 kilometers, kilometers since your last fill, based on your entries, and optionally, the direct fuel expense per kilometer and your approximate cost for the current fill.
