What is the difference between a newton and a kilogram?

Answer 1

Kg is an unit of mass and newton is an unit of force.

Weight(gravitational force acting on object) of an object on the surface of Earth, for example, is calculated:

m * g = F

For a 10 kg body, that force is roughly equal to 98.1 N.

Answer 2

F= mg, where g = 9.80665 m/s2 or N/kg, thus in order to get newton multiply mass in kilograms by 9.8.

Often people use the above "conversion". However there is no actual conversion. They are different units, one is mass and the other force (or weight). It is like asking how many pounds in a metre?

Using the formula F=MA, where force (weight) is measured in Newtons and Mass in Kilogram and Acceleration due to gravity in metres per second squared. This gives:

1 Newton = 9.80665 kg/m.s.s

You cannot however ignore the metres per seconds squared.

As the thorny question of why our political leaders started, totally incorrectly, using Kg for weights, would take too long to explain (or understand).

Answer 3

newtons measure weight which is the force of gravity that pulls you to the earth, where as kilograms measure mass, how heavy you are.

Eg. When you are at the moon your weight in newton dropps by a lot as there is no gravity, but your mass is still the same if you weigh 50kg on earth you'll weigh 50kg on the moon.
