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

It quantifies the amount of thermochemical British thermal units of thermal energy transferred per minute through one square foot of surface area.

Why convert to Btu (IT)/second/square foot?

Converting allows comparison and reporting of heat flux density with a unit expressing energy transfer per second, often needed in fire testing and high-temperature research.

Are there any accuracy concerns with this conversion?

Minor discrepancies can occur due to different definitions of British thermal units and must be considered when using this conversion.
