The weight of a body when measured on earth is the resultant force the ground applies to balance the force due to mass of the <em>body and acceleration due to gravity.</em>
Because your weight depends on the gravity you would weigh less on a planetary body with less gravity than on Earth, and in space you would weigh almost nothing at all. So the answer is <em>less than 38 kg</em>
It is <em>measured in Newtons (N)</em>. The weight of a person changes with varying gravity. As such the mass of the body varies through the universe irrespective of the <em>gravity and other external factor</em>. It is measured in kilograms.
