What does calorie (IT)/hour measure?

It measures the rate of energy transfer equivalent to one International Table calorie per hour, representing very small steady heat flow rates.

Why convert calorie (IT)/hour to kilocalorie (th)/second?

Converting helps translate small heat flow rates from older or laboratory units into larger, engineering-scale units useful in HVAC and thermal power analysis.

Are calorie (IT) and kilocalorie (th) exactly the same?

No, they are based on different calorie definitions: International Table calorie for cal (IT) and thermochemical calorie for kcal (th), which may introduce minor differences.
