What does joule per second measure?

Joule per second (J/s) is the SI derived unit of power, measuring the rate of energy transfer, and it is exactly equal to one watt.

When should I use kilocalorie (th)/second?

Use kilocalorie (th)/second to express power in terms of heat transfer, especially in thermal engineering and when working with calorie-based energy units.

Is kilocalorie (th)/second an SI unit?

No, kilocalorie (th)/second is not an SI unit and is typically used in specialized fields or regions favoring calorie-based measurements.
