What does kilocalorie (th)/second measure?

It measures the rate of heat transfer expressed as thermochemical kilocalories per second, commonly used for thermal power in heating systems.

Is electric horsepower the same as mechanical horsepower?

No, electric horsepower is standardized at 746 watts and differs from mechanical or metric horsepower units, which are not interchangeable.

Tips & Best Practices

Always verify that the calorie definition used matches the thermochemical standard
Understand that kilocalorie (th)/second represents thermal power, while horsepower (electric) is for electrical/mechanical power
Use this conversion to estimate equivalent power levels, but consider system efficiencies separately
Refer to motor nameplates and engineering documentation for precise power requirements

Limitations

The units represent different power types—thermal versus electrical/mechanical—so conversions assume direct equivalence without factoring in efficiency losses
Kilocalorie (th)/second depends on the thermochemical calorie definition, which must be applied consistently
Electric horsepower is standardized at 746 watts and differs from other horsepower units, which are not interchangeable with electric horsepower
