Mass (M) is the amount of substance in an object. Weight (W) the force that acts upon the object of a certain mass when placed in an environment that has a certain gravitational acceleration (g).
Equation:
Weight = Mass x Gravitational acceleration.
W = M x g
On Earth, g = 9.81 meters per second squared. Which is nearly 10 meters per second squared.
So if you weigh 100 Newtons on Earth, therefore your mass would be 10 Kilograms.
There is a misconception on weight being in Kilograms, but scientifically, weight is a force and should be in Newtons, and Mass is in Kilograms.
So let me see if you understand me clearly. In space, the amount of matter in a certain object doesn’t change, so the Mass of the object is the same everywhere. But there is no gravitational pull in space, it is equal to zero. So consequently, the weight of any object in space is zero.
I hope this helps.
