Why does the conversion from horsepower to calorie (th)/hour produce large numbers?

Because calorie (th)/hour is a very small unit of power compared to horsepower, resulting in large numerical values when converting.

Is calorie (th)/hour the preferred unit for power in technical use?

No, watts are generally preferred as the SI unit for power in precise technical contexts.

Can I use this tool for comparing engine power to heat transfer rates?

Yes, the converter is useful for expressing mechanical power as thermal power rates for scientific and engineering analysis.
