What does CHU/hour/square foot measure?

It measures heat flux density as thermal energy transfer rate per unit area, specifically CHUs delivered or removed each hour across one square foot.

Why convert CHU/hour/square foot to foot pound/minute/square foot?

This conversion helps translate heat flux data from a common HVAC unit to an imperial unit used in older U.S. engineering documents and legacy systems.

Is this conversion valid for all heat flow situations?

No, it assumes steady-state heat flux conditions; transient or time-varying heat flow needs more complex analysis.
