What does 1 joule per second represent?

It is the SI derived unit of power equal to one watt, representing the rate at which energy is transferred per second.

When should I use kilocalorie (th)/hour instead of watts?

Kilocalorie (th)/hour is commonly used in heating, ventilation, and appliance specifications to describe thermal power or heat transfer rates.

Is the conversion from joule/second to kilocalorie (th)/hour exact?

The conversion rate is precise for steady-state power transfer but should be applied carefully in non-uniform or transient conditions.
