How do you convert kilograms into newtons?

The problem is ; " Calculate the weight of a 5-kg box in a newtons. Remember the force of gravitiy on the earth is 9.8 m/s squared."

ALL I REALLY NEED TO KNOW IS HOW TO, IM NOT BEGGING FOR ANSWERS.

The weight of an object is measured in newtons (which is a unit of force). Its mass is measured in Kilograms. To determine the weight of an object, multiply its mass by the acceleration of gravity, abbreviated as g and measured in meters per second squared. Hence:

Weight (in Nt) = mass (Kg) x g (m/s^2)

The question as posed uses the word "force" improperly - where it says "the force of gravitiy on the earth is 9.8 m/s squared" it really should say "the acceleration due to gravity is 9.8 m/s squared." I suspect that the teacher's sloppiness here just adds to the students' confusion.

As described in the earlier postings - if you know an object's weight on earth in Newtons, divide by 9.8 m/s^2 to find out what its mass is. However, if you're on another planet whose acceleration due to gravity is something other than 9.8 m/s^2, you would have to divide the object's weight in Newtons as measured on that plant by whatever the acceleration due to gravity is for that planet.
