A physical interpretation is a height that a quantity of fuel could lift itself in the Earth's gravity field (assumed constant) by converting its chemical energy into potential energy. for kerosene jet fuel is 2,376 nautical miles (4,400 km) or about 69% of the Earth's radius.
distance per vehicle per unit fuel mass; e.g., km/kg. [11] distance per vehicle per unit energy; e.g., miles per gallon equivalent (mpg-e). Energy consumption (reciprocal efficiency) [3] is expressed terms of fuel consumption: [2] volume of fuel (or total energy) consumed per unit distance per vehicle; e.g. l/100 km or MJ/100 km.
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific .
Fuel consumption monitor from a 2006 Honda Airwave. The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally ...
For this reason, the useful load fraction calculates a similar number, but it is based on the combined weight of the payload and fuel together in relation to the total weight. Propeller-driven airliners had useful load fractions on the order of 25–35%.
Fuel fraction is a key parameter in determining an aircraft's range, the distance it can fly without refueling. Breguet ’s aircraft range equation describes the relationship of range with airspeed , lift-to-drag ratio , specific fuel consumption , and the part of the total fuel fraction available for cruise, also known as the cruise fuel ...

A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
