What does foot pound-force per hour measure?

It measures mechanical power as the work done or energy transferred, expressed as one foot pound-force performed every hour, representing very small power levels.

When should I convert foot pound-force/hour to horsepower?

You convert when comparing legacy mechanical power specifications or updating older imperial units to a standard and more widely recognized horsepower rating.

Is foot pound-force/hour suitable for high-power engines?

No, this unit is intended for very low power levels and is not practical for measuring large engine output.
