S.I.
Base Unit of Mass=Kg => 1 Kg =9.81 N( Because F=ma Here for free fall a=g=9.81 so,

F=mg=1*9.81=9.81 Newton).
Force=Newton (N).
Energy=joule(J)=>Kg x m^2 / s^2 ( So here Also can Used 9.8 Because its related to Kg).
Power = Watt(W) =>Kg x m^2 / s^3 (So here Also can Used 9.8 Because its related to Kg).
