Limitations
-
Horsepower/square foot is a non-SI mechanical power unit, while Btu (th)/second/square foot is a thermal energy flux unit
-
Conversion assumes equivalence in the context of heat flux density, which could vary in sensitive applications
-
This conversion is designed for imperial units and does not convert to SI units like watts per square meter
-
Measurement precision and unit definitions might cause minor discrepancies
Frequently Asked Questions
