What does kilowatt per square meter measure?

It measures heat flux density, indicating the rate of heat transfer per unit area, applicable to radiative and conductive/convective fluxes.

Why convert to kilocalorie (IT)/hour/square foot?

This unit is often used in HVAC and building energy calculations where calorie-based measurements are preferred or traditionally applied.

Are kilocalorie (IT)/hour/square foot and watts per square meter directly comparable?

They measure the same physical quantity—heat flux density—but use different unit systems with a specific conversion rate.
