Question

If the weight of a body is expressed in gwt then in what unit its mass will be expressed .convert 150 gwt into its mass SI unit.

Answer 1

SI unit of weight is Newton (N)
SI unit of mass is kilogram (kg)

weight(W)=150gwt
1 gwt is the force exerted by a body of mass 1 gm due to gravity
150 gwt is the force exerted by a body of mass 150 gm due to gravity
so mass (M)= 150gm
                    = 150/1000 kg
                    = 0.15 kg answer

Answer 2

150 gwt = 150*9.8N = 1470N
