What applications use heat flux density measurements?

Heat flux density is used to specify solar irradiance, quantify heat loss or gain in buildings, and describe radiative or convective heat transfer in industrial and HVAC systems.

Are there any considerations for conversion accuracy?

The conversion assumes steady-state conditions and uses the International Table kilocalorie definition; differences in definitions or transient conditions can impact precision.
