Frequently Asked Questions
-
What does Btu (th)/second/square foot measure?
-
It measures the rate of heat transfer per square foot area using British thermal units per second, commonly in engineering and building science.
-
Why convert to foot pound/minute/square foot?
-
This unit is preferred in some legacy engineering documents and thermal flux reports using imperial energy and time units.
-
Is this conversion widely used globally?
-
No, it is mostly used in regions or industries relying on imperial units, as SI units typically dominate scientific measurement.
