What does CHU/hour/square foot measure?

It measures heat flux density by indicating thermal energy transfer rate in CHUs per hour over one square foot of surface area.

Why convert to calorie (IT)/hour/square centimeter?

This conversion is helpful for comparing heat flux measurements on smaller surfaces or in laboratory settings that use calorie-based units.

Are these units part of the SI system?

No, both CHU/hour/square foot and calorie (IT)/hour/square centimeter are non-SI units commonly used in specific regional or historical contexts.
