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

It quantifies the rate of heat flow per unit area, representing one British thermal unit transferred per minute across one square foot.

When should I use erg/hour/square millimeter?

Use it for reporting fine-scale heat transfer in laboratory, microelectronics, or astrophysical contexts where CGS units are preferred.

Why is the conversion factor so large?

Because it accounts for differences in energy units, time intervals, and area scales between the two measurement systems.
