What is electric horsepower?

Electric horsepower is a power unit used to rate electric motors, defined exactly as 746 watts representing mechanical work by an electric machine.

Why convert horsepower to Btu (IT)/second?

Converting allows integration of mechanical motor power ratings with thermal energy units useful in heat transfer and HVAC engineering.

Is this conversion accurate for all horsepower types?

No, this conversion specifically applies to electric horsepower; other forms may need different conversion factors.
