The symbol W denotes the work done and m is the mass and g is the acceleration due to gravity. If m is in Kg and g has a unit of m/s². Then the unit Kg m/s² is equal to one joule J. That is the unit of work done. What is work done? Work done in physics is the dot product of force and displacement. Work done of one joule is equal to the force of one newton, exerted by an object of mass m and acceleration a. Thus we have F = Ma. If the acceleration is replaced by acceleration due to gravity g, then force of one Newton is mg, that is the product of mass and acceleration. Force is an external agent act on a body to change its state from rest or motion. If the force applied causes a displacement of the object, then a work is done on the body. Let the mass is taken in Kg and acceleration due to gravity is in m/s², then one newton  is  Kg m/s² is equal to one joule J. Hence, W has the unit of Kg m/s² or J.
