NO, they are not the same.
Mass is the amount of matter in an a body or object.
Weight is the force exerted by gravity on a body or object.
Take this case:
Moon's gravity is 1/6 of earth's gravity. If we bring a bike a with a mass and weight of 12 kg from earth to the moon, it's mass will still the same but the weight will be 2 kg only because of the weak gravity (gravity pull) of the moon compared to earth.
