What does one horsepower (metric) hour represent?

It is the energy produced by sustaining one metric horsepower, equal to about 735.49875 watts, for one hour.

Why use calorie (IT) instead of joules for energy conversion?

Calorie (IT) was historically used in steam tables and classical thermodynamics, making it useful for interpreting older engineering data.

Is this conversion suitable for modern engineering calculations?

This conversion is mainly relevant for analyzing legacy data; modern engineering typically uses joules or kilowatt-hours.

Can I convert fractional horsepower hours using this tool?

Yes, fractional values like 0.5 horsepower (metric) hour can be converted accurately.
