To be more specific about what I'm looking for, it is Thrust specific fuel consumption. As in mass of fuel used In a given period of time/thrust produced over that period of time. http://en.m.wikipedia.org/wiki/Thrust_specific_fuel_consumption Which has a lower TSFC? Rockets or Jets...

What I am still confused about is why. Jet engines have to compress the air and require energy (fuel) to turn the turbines while rockets already have the compressed air, so they can skip the turbine compression part of the jet engine. Wouldn't that make rockets engines more fuel efficient per...

You said per unit time. Is there a measure of efficiency based on distance and not time. It is understandable that it is more efficient based on time. But rockets are generally faster. Do you know which is more efficient based on time?

Sorry I was unclear, I was referring to energy efficiency, as in how much of the energy is used for propulsion, and how much is wasted.

Which are more efficient, Rocket Engines or Jet engines, and why? It would make sense that rocket engines are more efficient because they aren't effected by air pressure but I have been told by some people that actually Jet engines are more efficient so I am confused. If you know of any link...
