Take note: 1 Newton = 1 kg-m/s²
                 1 kg. = 2.21 lbs(pounds)

For mass in kilograms, use the conversion factor above:

So we will have:

        100 lbs x ( 1 kg / 2.21 lbs ) = 45.25 kg mass Answer.

For weight in Newton:

         W = mg         m = mass in kg               g = 9.81 m/s² (acceleration due to gravity)
         W = 45.25 x 9.81
         W = 443.9 Newtons  ANSWER
