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

It measures the rate of thermal energy transfer per unit area, specifically one British thermal unit per second passing through one square inch.

When should I use erg/hour/square millimeter units?

These units are ideal for expressing heat flux in small-area laboratory experiments, microelectronic thermal studies, or CGS-based radiative flux measurements.

Why is the conversion factor so large between these units?

The large factor arises due to differences in energy unit scales, as well as time and area units being in hours vs seconds and square millimeters vs square inches.
