Frequently Asked Questions
-
What does horsepower (metric)/square foot represent?
-
It measures heat flux density as the power of one metric horsepower spread over one square foot of area, indicating the rate of heat transfer per area.
-
Why convert to foot pound/minute/square foot?
-
This unit is often used in older U.S. engineering and HVAC documents to describe heat transfer rates using imperial energy, time, and area units.
-
Is this conversion useful for modern applications?
-
Yes, it helps reconcile legacy heat flux data with modern engineering standards and SI units, especially in thermal system documentation and analysis.
