F = GMm/R² where * F is the force of attraction between two objects * G is the universal gravitational constant; G = 6.67*10-11 N-m²/kg². The units of G can be stated as Newton meter-squared per kilogram-squared or Newton square meter per square kilogram. * M and m are the masses of the two objects * R is the distance between the objects, as measured from their centers * GMm/R² is G times M times m divided by R-squared this is newtons gravity equation, it is not as accurate as einsteins but in this case it should do the trick. there is more on this website: http://www.school-for-champions.com/science/gravity_universal_equation.htm
Knowing your mass or weight on Earth allows you to calculate what the mass or weight would be on the moon.
Weight (W) and mass (m) are different.
In what follows, weight is measured is either Newtons or pounds.
Mass is measured in kilograms.
W=m a (mass times acceleration due to gravity).
On Earth, gravity = 9.8 meters/second/second.
On the Moon, gravity = 1.622 meters/second/second.
Gravity on the Moon is one sixth of what gravity is on the Earth.
A person with a mass of 120 kilograms has the same mass on Earth as on the Moon.
Here are some examples. Notice the units.
1. A large person with a mass of 120 kilograms.
A person with a mass of 120 kilograms has an Earth weight of 1176 Newtons which is 264 pounds.
A person with a mass of 120 kilograms would weigh 196 Newtons on the Moon which is 44 pounds.
2. A medium size person weighing 120 pounds on Earth.
A person weighing 120 pounds on Earth would weigh 20 pounds on the Moon.
A person weighing 120 pounds on Earth would weigh 529 Newtons on Earth.
A person weighing 529 Newtons on Earth would weigh 88 Newtons on the Moon.
A person weighing 120 pounds on Earth has a mass of 54 kilograms everywhere.
3. A child who weighs 120 Newtons on Earth.
A child weighing 120 Newtons on Earth has a mass of 12 kilograms everywhere.
A child weighing 120 Newtons on Earth would weigh 20 Newtons on the Moon.
A child weighing 120 Newtons on Earth would weigh 27 pounds on the Earth.
A child weighing 27 pounds on Earth would weigh 4.5 pounds on the Moon.
120 kg of mass weighs 1176.8 newtons (264.6 pounds) on Earth,
and 194.8 newtons (43.8 pounds) on the Moon.
A person weighing 12kg on the moon (264 lb and 8.87 oz) would weigh approximately 724kg on Earth (1596 lb and 2.34 oz).
About 1/6 as he weighs on Earth. From the Wikipedia, gravitation on the moon is 1.622 m/s2; this is equivalent to 1.622 N/kg. So, (100 kg) x (1.622 N/kg) = 162.2 Newton.

A man that weighs 60 kg on Earth would weigh less on the moon. He would weigh 9.9 kg on the moon.
You would weigh approximately one-sixth of what you weigh on earth, so 11 2/3 kg.
Work it out yourself... You need to calculate the newtons of force that 4.5 stone is on the moon... On earth, someone who is 100 kg is 100 x 9.81 (gravity). That's their Newton weight on earth. Find the value for gravity on the moon and substitute it in... Nothing in life is free
The question is ill-posed. Weight is mesured in Newtons (N) as it's a force, it's mass is measured in kg. There are ctually two questions mixed together here. Let's answer both: 1) If an astronaut has a mass of 100kg on earth what is his mass on the moon? 100kg - put him on a frictionless surface and try and accelerate him, it's just has hard on the moon as on earth (or anywhere else for that matter). 2) If an astronaut weighs 981N on the surface of the earth (as an astronaut of mass 100kg would) how much does he weigh on the moon? Surface gravity on the earth is 9.81m/s/s which is how we end up with the 100kg astronaut weighing 981N. On the moon surface gravity is only 1.62m/s/s so the same astronaut would weigh 162N - about 1 sixth that on earth.
one sixth just over 8 kg
1 kg
A man that weighs 60 kg on Earth would weigh less on the moon. He would weigh 9.9 kg on the moon.
1 kg mass would weigh about 167 grams on the moon.
100 kg
0.4 kg
1.6 kg
About 1/6 of what you weigh on Earth. For example, if you have a mass of 60 kg, on Earth you weight about 600 N, while on the Moon you would weight about 100 N.
100*4.3 = 430 kg!
About 100-115kg.
1600 kg
You would weigh approximately one-sixth of what you weigh on earth, so 11 2/3 kg.
2 kg.
