This calculator calculates the amount of energy required to complete a journey, along with the power needed to accomplish each stage.
It segregates the journey into [up to] ten altitude variations (10-stages).
Energy may be used to determine the quantity of fuel required to complete the journey, or any stage thereof. Fuels are generally qualified by the energy available per unit mass (Joules per kilogram or foot-pounds per pound).
Power is the rate of energy expenditure (energy intensity) required to complete a given stage of the journey. This value may be used to calculate the rate of fuel consumption (kilometres per litre or miles per gallon) for that particular stage.
This calculator takes into account rolling resistance and wind resistance.
