1/6 of the weight on Earth or 20 kgs.

120Kg = 19.9Kg
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 the earth's gravity — 1/6 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 :-)

Kgs (kilograms) are a measure of mass, which isn't affected by the gravity acting on it. A person's mass doesn't change with a changing gravity field, but a person's weight (usually measured in pounds or stones) does. Weight is the pull of gravity on an object.
If a person is 120kgs on earth, he will be 120kgs on the moon.
If however he weighs 120lbs, he will weigh 20lbs on the moon.

The gravitational pull of the moon is 1/6th of the pull exerted by earth. So the man's weight on moon will be (1/6) * 120 = 20 kg.

First of all, 120 kg is his mass. Not his weight. (Scientifically, that is. But there has been a simple yet MAJOR misunderstanding that happens since...forever!)
Mass is always the same, no matter where he is or how much the gravity is.
Weight (Newton)=mass (kg) x gravity (N/kg).
The gravity on earth is 10 (or 9.8 to be exact). So the man's weight on earth is 1200 N (Newton). Moon's gravity is 1/6 of the earth's so on the moon he would be 200 N.

If a man weighs 120 kg. on earth, and he sets a metric scale on the surface of the moon and stands on it, he will weigh approximately 20 kg. Kilograms is the European dominant measuring unit, and originated as being the weight for one liter of water. Americans don't use kilograms unless they are weighing cocaine, so when we go back to the moon, we'll take a pound scale with us.

Without being overly technical, it would be 20 kg because gravity on the Moon is 1/6 of that on Earth.
Being technical, kilogram is a measure of mass and not weight. Mass does not change with gravity. Mass is measured in kilograms in the metric system and in slugs in the English system. Weight is measured in Newtons in the metric system and pounds in the English system. But only technical people have ever heard of Newtons or slugs and most people use kilogram to mean the weight of a kilogram of mass and pound to mean the mass of a pound weight.

gravity on the moon is 1/6 of that on earth

so 1/6* 120=20 kgs
good luck

Hey. What's Up. That guy would still weigh 120kg. :D

If his mass is 120kgs on earth, his weight on EARTH would be w=mg=120kg*9.8ms^-2=1176N.
His mass on MOON would be 120kg.(since mass doesn't change). and w=120kg*((9.8ms^-2)/6) = 196kgms^-2
(since acceleration due to gravity on moon= 1/6 times acceleration due to gravity on earth.)
