Why convert between kilocalorie (IT)/hour/square foot and Btu (IT)/second/square foot?

Conversion facilitates comparing heat flux data across different engineering fields, such as from building energy modeling to fire testing and high-temperature material evaluations.

What does the conversion formula represent?

The formula converts the amount of thermal energy transferred per unit area per hour into the amount transferred per unit area per second using corresponding energy units.

Are the units interchangeable without conversion?

No, because they represent heat flux over different time bases and unit systems, conversion is necessary for accurate comparison and reporting.
