What is a calorie (th)/second?

It is a unit of power representing one thermochemical calorie of energy transferred per second, exactly equal to 4.184 watts.

What does calorie (IT)/hour measure?

It indicates power by measuring the energy transfer rate of one International Table calorie per hour, representing very small heat flow rates.

Why is the conversion factor so large between these units?

Because it involves differing calorie definitions and converts seconds to hours, resulting in a large multiplier when converting calorie (th)/second to calorie (IT)/hour.
