Your weight on the moon is a function of the moon's gravity. First, we know that gravity is a force that attracts all physical objects towards each other (but why this happens is largely unknown!). Second, the greater the mass of an object, the stronger the force of gravity.

The moon is 1/4 the size of Earth, so the moon's gravity is much less than the earth's gravity, 83.3% (or 5/6) less to be exact. Finally, "weight" is a measure of the gravitational pull between two objects. So of course you would weigh much less on the moon. Imagine how far you could jump on the moon! The Apollo astronauts apparently had fun :-)

* The "Units" selection doesn't affect the calculation -- the gravity of the moon is always 1/6 of whatever unit you're using. Also note that strictly or scientifically speaking, the kilogram is a unit of mass, the value of which is unaffected by gravity. Gravitational force or weight should technically be expressed in newtons (kilogram-force) under the metric system, and "pound-force" under the English system. In common, non-scientific usage, however, "pounds" and "kilograms" are understood to refer to weight and hence suits the purposes of this calculator, which is to compare the relative force of gravity on the Moon and Earth.
