What is the difference between calorie (IT) and calorie (th)?

Calorie (IT) refers to the international-table calorie while calorie (th) denotes the thermochemical calorie; they differ slightly in energy value definitions.

When should I convert from calorie (IT)/s/cm² to calorie (th)/s/cm²?

Conversion is important when handling legacy or cross-disciplinary thermal data to ensure uniformity despite the subtle calorie definition differences.

Why is this conversion important if the values are close?

Even a small difference matters in precise thermal engineering and calorimetric measurements where accuracy is critical.
