What does joule/second/square meter measure?

It measures heat flux density, representing the rate of heat flow per unit area and equals one watt per square meter.

Why use CHU/hour/square foot instead of SI units?

CHU/hour/square foot is commonly used in HVAC and building industries within imperial unit systems, making it easier to specify thermal performance and equipment sizing.

What should I watch out for during conversion?

Ensure that CHU energy equivalence and area/time unit differences are correctly applied to maintain conversion accuracy.
