Because weight is a mathematical function of mass and gravity.

Weight isn't constant, but is dependent on the force of gravity. The force of gravity, on Earth, varies slightly from location to location (I miss my geologist ex-girlfriend). Take note that your object would have the same amount of matter wherever it went -- but on the moon, it would weigh one-sixth what it does here on Earth.
The measurement you'd want to get for better consistency would be the mass. You can get this by using a balance, and balancing your object against known masses.

The mass of an object is a constant anywhere in the universe. Force, which we measure in kilograms, is a function of the accelleration of a mass F=ma. Weight, which we measure in newtons, is a function of gravitational attraction, which causes accelleration, F=mg. Gravitational force is different on every body in the universe. Therefore, weight will vary throughout the universe, though mass remains constant.

because weight depends on where you are when you measure it. If you are on the moon, then weight is completely different. If you are in space, weight is zero.
Mass, on the other hand, is a measure of the amount of a substance, not the weight of it. But we estimate mass by using weight on a scale, since weight is fairly constant on earth.

Weight is a reflection of the mass in a specific gravity, so change the gravity and you change the actual number (weight). therefore, weight is a relative value - relative to the mass of the object in a certain gravity.

Weight differs; depending on where on earth -- or in the universe you are.
If you are aloft enough (above the earth) your weight will be less than at the earth's surface. If you're on the moon your weight will be about 1/6 what it is on the earth. Yet in any instance your fundamental MASS has stayed the same.

no, i'm not going to.
you do it, and say i gave you the answer.
