What does erg/hour/square millimeter measure?

It measures heat flux density as the amount of energy transfer (in ergs) per hour through one square millimeter of area.

Where is horsepower/square foot used?

It is used to express power per area in thermal applications like burner ratings, furnace heat input, and solar power concentration.

Why is the conversion factor so small?

Because erg/hour/square millimeter is a very small unit compared to horsepower/square foot, requiring a tiny scaling factor in the conversion.
