The S.I unit of force is newton. The C.G.S unit of force is dyne.
One newton is the force which when acting on a body of mass 1 kg produces an
acceleration of 1 m/s2 in it.
1N=1kg*1m/s2
=1000g*100cm/s2
=100000 g cm/s2
=105 dyne

work is said to be done only when the force applied on a body makes the body
move....i.e there is a displacement of the body
S.I. unit of work is joule.
1 joule of work is sais to be done when a force of 1 newton displaces a body
through 1 metre in its own direction
