What does Btu (IT) inch/hour/sq. foot/°F measure?

It measures thermal conductivity as the heat transferred per hour through a material 1 inch thick per square foot area with a temperature difference of one degree Fahrenheit.

Why convert thermal conductivity units between these systems?

Converting units allows comparison and application of thermal conductivity data between North American customary units and metric calorie-based units used in different building and HVAC standards.

Can this conversion be used for non-steady-state heat transfer?

No, the conversion applies under steady-state heat flow conditions and assumes homogeneous material thickness.
