The unit for the amount of substance (mass) in the FPS system is the pound.
You are probably confusing energy for power. A 'unit', which is short for 'Board of Trade Unit', is equivalent to a kilowatt hour, which is used to measure energy, notpower.
The SI unit for power is the watt, symbolized as W.
There is no SI base unit for power.Power is measured in watts, which is a derived unit, not a base unit.A watt is equal to one joule (newton-meter) per second (J/s).
Power is the rate of use of energy in time. The unit of Energy is joule and the unit of Power is joule/second or Watt.

degree Fahrenheit which is used in UK and FPS system
The unit of electric current is amperes (A), not frames per second (fps). Frames per second is a unit used to measure video or screen display speed.
In the fps system, the unit of acceleration is feet per second squared (ft/s^2).
FPS (foot-pound-second) is a unit of energy in the imperial system. It is defined as the work done when a force of one pound is applied over a distance of one foot.
It could be pounds per cubic inch, or pounds per cubic foot, or tons per cubic yard. The only substance I know in fps is water which is 62.4 pounds per cubic foot.
In the foot-lb-sec (FPS) system, an appropriate unit would be cubic feet per second (CFS). A more common unit is gallons per minute (GPM). 1 GPM = .00223 CFS.
