What does Btu (th)/second/square inch measure?

It measures the rate of heat energy transfer per second through a one square inch area, representing heat flux density in imperial units.

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

This unit is commonly used in building energy calculations and insulation performance assessments which use calorie-based heat flux measurements.

Are these units interchangeable without adjustment?

No, they differ significantly in scale and typical use; careful conversion is needed to maintain accuracy and relevance.
