What does kilowatt/square meter measure?

Kilowatt per square meter measures the rate of heat energy transfer per unit area in metric units, useful for radiative and conductive heat flux evaluations.

Are there any accuracy concerns when converting between these units?

Yes, accuracy depends on the exact definition of the CHU and measurement precision, with potential amplification of small errors due to the large conversion factor.
