What is foot pound-force per second used for?

It measures mechanical power in imperial units, often used for small hand tools, engines, and mechanical engineering applications involving torque and rotational speed.

Why convert foot pound-force/second to kilojoule/hour?

To translate mechanical power expressed in imperial units into an energy transfer rate that is commonly used on an hourly basis, useful for energy comparisons and reporting.

Are there any limitations when converting between these units?

Yes, the conversion assumes steady-state power and the units differ in time scale and measurement system, so interpretation must consider these factors.
