What does one pound-force foot represent?

It represents the work done by a force of one pound-force acting through a displacement of one foot in the force's direction.

Is pound-force foot the same as torque?

Although pound-force foot shares units with torque and is used in torque contexts, torque and energy are physically different quantities.

What equals one kilowatt-second in joules?

One kilowatt-second equals one kilojoule, which is 1000 joules.
