82 kg of mass weighs 803.6 newtons (180.78 pounds) on Earth.

From Wikipedia, the gravitational acceleration on the Moon (on its equator) is 1.622 m/s2. This is the same as 1.622 N/kg, so you can multiply the mass by this number to get the weight in Newton. (The man's mass, of course, will still be 70 kg on the Moon. His weight will change, but his mass will not change.)
Weight = mg (mass x gravity).
Weight is a measure of the gravitational pull for a mass , such that a mass of 1 Kg is having a weight of 10 Newton . So weight is a downward force measured in Newtons . Weight ( in N ) = Mass ( in Kg ) × Gravity ( usually 10N/Kg )
If a student had a mass of 195 kg, then his weight on earth was 1,911 newtons, or about 430 pounds.
No. Mass is measured in kilograms. Weight is measured in Newtons.
If you are 36 and your weight is 82 kg, the weight you want to lose depends on many factors. Some factors are your height and metabolism.

On my planet a man with a mass of 90 kg has a weight that is also 90 kg. On the Moon the same 90 kg man has a weight of 15 kg because the Moon is smaller and has less gravity. We distinguish between mass (amount of matter) and weight (a downward force) so that mass stays the same wherever the man is, even if his weight changes. Since Isaac Newton's time we know that force is equal to mass times acceleration, and the unit of force is defined technically as the force that accelerates a mass of 1 kg by 1 metre per second, every second. That amount of force is a Newton. If a 1-kg mass is dropped it will accelerate downwards at 9.806 metres per second per second, therefore the force on it is 9.806 Newtons. So the weight of a 90 kg man is technically described as 90 x 9.806 Newtons, in other words 882 Newtons. On the Moon his mass is still 90 kg but his weight is now only 147 Newtons.
he will have a lower weight (newtons) but mass (KG) will stay the same.
An object with a mass of 1.0 kg has a weight of 9.807 newtons.
If the 82 kg of mass is on the Earth's surface, then it weighs 180.779 pounds. (rounded) If it's in some other place, then it weighs something different. There's no firm, constant, direct relationship between mass and weight everywhere.

'Kg' is a unit of mass, not weight. On Earth, 1 kg of mass weighs 9.8 newtons, and 1 newton is the weight of about 0.102 kg of mass. On the moon, the same kg of mass weighs 1.6 newtons, and 1 newton is the weight of about 0.616 kg of mass. On Mars, the same kg of mass weighs 3.7 newtons, and 1 newton is the weight of about 0.269 kg of mass.
Weight is mass multiplied by acceleration. The man's mass is 82 kg. The acceleration due to earth's gravitational attraction at sea level is 9.81 m/s/s. The man's weight would be 800 kg m/s/s or 800 Newtons. Notice that the value was rounded to the tens place since the factor with the least precision was precise to two digits. Strictly speaking, a bar should be placed over the zero in the tens place.
