What does one kilocalorie (IT) per second represent?

It represents a unit of power equal to one kilocalorie defined by the International Table calorie transferred per second, equivalent to 4,186.8 joules per second.

Why convert kilocalorie (IT)/second to Btu (th)/second?

Conversion helps translate older or physiological heat power data into units compatible with modern HVAC, industrial, and thermal energy management systems.

Can I use this conversion for dynamic heat transfer analysis?

No, the conversion assumes steady power transfer rates and does not account for transient thermal phenomena which may require specialized analysis.
