The fundamental measure of rocket engine performance is the mass of propellant that can be propelled out the back of the rocket and at what speeds. The performance of a rocket engine depends on the thrust, which is generated relative to the size or weight of the propulsive device. 

The most important metric for the efficiency of a rocket engine is specific impulse, which is measured as a speed or a time. The higher the specific impulse, the less propellant is required to provide the desired impulse. 

The performance of a rocket is determined by the propellant flow rate (Mo) in kilograms/second and the effective exhaust velocity (Ve) in meters/second.
