Weight” in this context is a colloquial term for “mass”. To see this, note that what an engineer means by the “power to weight ratio” of an electric motor is not infinite in a zero gravity environment. Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds. In classical mechanics, instantaneous power is the limiting value of the average work done per unit time as the time interval Δt approaches zero. This fact allows one to express the power-to-weight ratio purely by SI base units.
Fuel cells and flow cells, weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Examples of high power, a rapidly falling torque curve would correspond with sharp torque and power curve peaks around their maxima at similar rotational speed, have the distinction of not containing the energy storage medium or fuel.
