What is a Btu (th)/second/square foot unit?

It measures heat flux density as the transfer of one British thermal unit (thermochemical) per second across a square foot area, used in Imperial unit applications.

What should be considered when using this conversion?

Unit consistency is important due to differences in base time and energy units; the conversion is specific to standard thermochemical Btu and International Table kilocalorie definitions.
