What does watt per square inch measure?

Watt per square inch measures heat flux density as the amount of power transferred per one square inch of surface area.

When should I use foot pound per minute per square foot?

Use foot pound per minute per square foot in legacy or imperial-based engineering documents to describe energy transfer rates across one square foot each minute.

Why is this conversion useful?

It helps translate concentrated power density measurements on small surfaces into larger-scale imperial units for thermal analysis and handling historical data.
