Frequently Asked Questions
-
What does horsepower (metric)/square foot measure?
-
It measures heat flux density as power in metric horsepower spread over one square foot of area, indicating the rate of heat transfer per unit area.
-
Why convert from horsepower (metric)/square foot to Btu (th)/minute/square foot?
-
Converting allows comparison and analysis of heat flux data in units commonly used in HVAC and thermal engineering, especially when handling legacy or mixed-unit data.
-
Is this conversion suitable for dynamic or changing heat flux conditions?
-
No, the tool assumes steady-state conditions and uniform heat flux for accurate conversions.
