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

It measures the rate of heat transfer per unit area, representing one British thermal unit of energy transferred each second across a square foot of surface.

Why convert from per second to per minute units?

Converting to per minute units matches measurement durations commonly used in HVAC and building energy calculations, aligning data with standard reporting intervals.

Can this conversion be used for fire testing?

Yes, it is often used to express incident heat flux levels in fire and material exposure testing where thermal energy transfer rate per area is critical.
