Inertia and force have different dimensional formulas.


#F=[MLT^-2]# and #I=[ML^2]#
Moreover force causes a change in the state of rest or motion of a body whereas inertia is only a property due to which it resists a change in it's state of motion or rest.
Inertia is the rotational equivalent of mass.
