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.
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.
Joule is a unit of energyWatt is a unit of power
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).

degree Fahrenheit which is used in UK and FPS system
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.
feet per second squared,
It is feet per second-squared.
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.
In FPS system of units, feet is the fundamental unit of length, one of the fundamental physical quantities.
