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
