Frequently Asked Questions
-
What does joule/second/square meter measure?
-
It measures the thermal power flow rate per unit area, quantifying heat flux density or irradiance in metric units.
-
Why convert to foot pound/minute/square foot?
-
This conversion helps interpret heat flux density in imperial units commonly used in U.S. legacy engineering and HVAC documentation.
-
Is the conversion exact for all practical purposes?
-
While based on a defined conversion factor, differences in unit bases and measurement conditions mean small rounding errors can occur.
