Weight is how much force is exerted on the body by gravity. It is measured in N. To get Weight you multiply the mass in kg by the gravitational force of the planet that you are on (about 9.81 for earth). Gravity causes weight, which is why if you are an in an impossible scenario where no gravity is acting on you your weight would be 0N.

Mass is how much matter something contains, measured in Grams. A body's mass always stays the same regardless of where it is.

The mass of an object is a measure of how much stuff it's made of.  So it's
a property of the object, like the object's length or color.  It doesn't depend on
where the object is located right now, or on what else is around it..

The weight of an object is the measure of the gravitational force between it
and something else.  The strength of the force depends on the size of both
masses, and also on how far apart they are.  So the weight does depend on
where the object is located right now, and on what else is around it.

I think that sums it up fairly well.
