What does a megaton measure in terms of energy?

A megaton is a non-SI energy unit representing the energy released by one million metric tons of TNT, typically about 4.184×10^15 joules.

Why convert megatons to horsepower hours?

Converting megatons to horsepower hours helps relate extremely large energy releases to mechanical energy concepts used in engineering and machinery output.

Are horsepower hour values consistent across all definitions?

No, horsepower hours can vary slightly depending on whether the mechanical (imperial) or metric (PS) horsepower definition is used, affecting joule equivalences.
