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

Calorie (IT) and calorie (th) differ in their calorie definitions, affecting the exact heat flux density value. This conversion adjusts for the small but meaningful difference in heat transfer rate calculations.

Why should I convert between these units?

Converting ensures alignment of measurements from different calorie definitions, which is important for accuracy in engineering standards, laboratory tests, and calibration.

Are these units commonly used today?

They are mostly used in legacy or specialized contexts; modern scientific work generally prefers SI units like watts per square meter.
