How much horsepower is there in 190-cc?

That's one of those questions that can't be answered without more refinement.

Is this posed as a displacement question? If so are we talking a steam engine, gasoline or diesel? At what point are you measuring the output? At the crank,

at the output shaft, after the transmission-before the wheel?

Is this refering to fuels? 190cc of oil, gasoline, uranium, wheat flour, water? What?
