In the first place mass is a scalar and weight a vector.
Mass will only have the magnitude and no direction whilst weight has the magnitude and direction. (always towards the center of the gravitational field)
Weight will always depend upon the gravitational field strength of the place where the mass is. On the other hand mass is constant and independent of the gravitational field strength.

Mass is a measure of an object's resistance to being accelerated, also called the inertia of an object. It is much harder to get an object moving if it has a large inertia (mass).
weight is the amont of force between two massive objects. We live next to a VERY massive object (Earth) so usually talk about weight as a measure of the force between object and the earth. And we describe that force as :
gravitational force=mass*g,
where g is a constant value at the surface of the earth (9.8 m/s^2). g is called "the acceleration due to gravity"
If you took the same object and put it near the moon, its inertial mass wouldn't change, but the gravitational force between it and the moon would be different than the gravitational force between it and the earth at the earth's surface. Its weight near the moon would be different but the mass would be the same. This is still true:
gravitational force=mass*g,
but g has a different value at the moon (~1/6 the value at Earth)

Weight is the gravitational force towards the earth while
Mass is the amount of matter within the body or object.
The amount of weight varies depending on its gravitational force while Mass is constant whatever amount of force applied on it.

Mass of a body is constant.
When we multiply mass with gravitational pull(G) it becomes weight. Hence weight of an object changes with changing values of G where as Mass is constant...

mass -- measurement of the amount of matter in an object, expressed in kilograms
(Really, mass measures both the inertia of an object and its response to gravity.)
weight -- measures the force of gravity on the object, expressed in Newtons
The relation between the two is
weight = mass * g
where g = 9.81 N/kg, or 9.81 m/s^2 is the "gravitational constant"

weight = mass*g. Weight is a force (c.f. f=ma, the force is weight and the accelleration the acceleration due to gravity).

mass is a constant the amout of mater in an object
weight is how much gravity pulls on it and varrys from planet to planet
