What does 1 kilocalorie (th)/hour represent?

It represents the transfer of one thermochemical kilocalorie of energy per hour, quantifying heat flow rate.

How is joule/hour related to watts?

One joule/hour equals one thirty-six hundredth of a watt, indicating a very low power rate.

Why convert from kilocalorie (th)/hour to joule/hour?

To translate legacy heat flow measurements into SI-compatible units for detailed engineering and thermal analysis.
