Expert Answer
One kilogram weight is the force exerted on an object of mass 1 kg by the earth.
We know that the weight of an object, W = mg
where m is the mass and g the acceleration due to gravity
So weight of an object of mass 1 kg will be:
When m=1 kg
W = 1 kg×9.8 m/s2
W = 9.8 kg m/s2
We know that 1 kg m/s2 = 1 N
i.e 1 kg-wt = 9.8 N
kg-wt is commonly used as the unit of weight.
