What does the unit foot pound-force/second represent?

It is an imperial power unit equal to one pound-force applied through a one-foot distance every second, used mainly in mechanical engineering calculations.

How is horsepower defined in this conversion?

This conversion uses mechanical/imperial horsepower defined as 550 foot-pounds per second, approximately 745.7 watts.

Why should I specify the horsepower variant?

Because different horsepower variants exist, like metric horsepower, specifying the variant ensures conversion accuracy according to context.
