Why are there two different calorie units for heat flux density?

The calorie (IT) and calorie (th) differ because they are based on International Table and thermochemical calorie definitions, respectively, which cause variations in heat flux measurement values.

Can I use this conversion for modern heat flux data?

This conversion is mainly for legacy or specialized applications where calorie-based units are still referenced; modern data typically use SI units like watts per square meter.

How precise is the conversion between these units?

The conversion uses a fixed factor but small discrepancies may occur due to differing calorie definitions and rounding in original measurements.
