What does joule/second/square meter measure?

It measures the rate of heat energy flow per unit surface area, equivalent to watts per square meter.

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

This unit is commonly used in HVAC and building energy analysis to express heat flux in calorie-based units, aiding comparison and reporting.

Can I apply this conversion to total heat energy?

No, this conversion is specific to heat flux density and must consider area and time separately for total energy calculations.
