What is the Unit of Weight? SI Unit, CGS Unit and Other ...

Therefore, the SI unit of weight can be measured in kg⋅m/s 2 (kilograms times meters per second squared) which is equal to a newton (N). Since weight is the force extended by the gravitational force on a mass it is represented by formula W = m*g, where weight can be kg * m/s 2 which is equal to N.
