Question

A kilogram is an SI unit. Which quantity might you measure in kilograms?

Answer 1

"Mass" is the one quantity that you would want to measure in kilograms. On the other hand, weight of an object is measured in Newton. There is definitely a relation between kilogram and Newton.

Answer 2

Well, Weight and the Planets are measured by kilograms. The SI unit of weight is Newton.

Since weight of a body is nothing but Mass of the body multiplied by acceleration due to gravity acting on it, the SI unit of weight will be the same as the SI unit of force (mass x acceleration), that is, Newton.

However, you may note that since the acceleration due to gravity is different on different heavenly bodies, the value of weight will be different on different bodies, unlike the mass, which is the same throughout the universe.

I hope this helps! :)
