What does CHU/hour/square foot represent?

It measures the rate of heat transfer per unit area as CHUs of thermal energy delivered or removed per hour across one square foot of surface.

When should I use calorie (th)/second/square centimeter units?

These units are typically used in laboratory calorimetry, fire testing, and historical data involving small-scale surface heat measurements.

Why is this conversion important in HVAC applications?

It allows translation between building-related heat flux units and those used in precise lab or radiative heat flux tests, supporting compatibility and comparison.
