What does Btu (IT)/second/square foot measure?

It quantifies the rate of heat transfer per unit area, expressed in British thermal units transferred every second across one square foot.

Why convert heat flux density to per minute units?

Converting to per minute units aligns measurements with common time intervals used in building thermal management and HVAC calculations.

Can this conversion handle rapidly changing heat flux rates?

No, it assumes a constant heat flux rate over the time period; variable fluxes may require more detailed timing analysis.
