You can't really convert kilograms to newtons, since they measure different things. The relationship is:weight = mass x gravity
For normal Earth gravity, you can use a factor of about 9.8 newton/kilogram for gravity.
100 newtons = 10.2 kilograms
There are 9806.65002864 Newtons in 1000 kilograms. Hope this helps!
Multiply mass in kilograms by 9.81 to get weight in Newtons
Force in newtons is equal to mass x acceleration. Earth's acceleration is 9.807 meters per second squared. Thus, 70kg x 9.807 = 686.49 newtons.
The mass of 19.6 Newtons is 1.99 kilograms at the earth's surface.
On earth, a mass of 2.26 kilograms weighs 22.15 newtons. (rounded)
45 newtons is about 4.6kg
A kilogram is a measure of mass, not of weight. A 70 pound dog will weigh 311 Newtons.
On earth, 1kg is 9.8 newtons.
On earth, two newtons is 0.204kg
On earth, 1.3 kilograms is 12.74N
On earth, 980N is 100 kilograms.
