What does foot pound/minute/square foot measure?

It measures heat flux density, representing energy transfer per unit area and time using imperial units.

Why convert to Btu (th)/minute/square foot?

Because Btu (th) units are commonly used in HVAC and thermal engineering, standardizing values improves communication and analysis.

Are there differences within Btu units affecting conversion?

Yes, thermochemical Btu might differ slightly from other Btu definitions, which can cause minor conversion variations.
