Your weight, measured in newtons (N), anywhere, is the product of your mass, measured in kilograms (kg), multiplied by acceleration due to the force of gravity, measured in metres per second squared (ms^-2).
Example: The average adult male is generally said to weigh 70 kg. On Earth acceleration due to the force of gravity is generally considered to be 9.8 ms^-2. Find the product of these two values = 70 x 9.8 = 686 kg ms^-2. This unit, kg ms^-2, is given the name, newton (N).
You can do this yourself. First, weigh yourself and if your scales do not give your weight (actually your mass) in kilograms convert your weight into kilograms using an online converter (there are many of them). Next look up the gravity of each of the celestial bodies you list and ensure the value is given in metres per second squared. Take you mass in kg and multiply it by the gravity of that celestial body and you will have your weight. A rough estimate to check if you are doing it correctly is to do the Earth first. You can round-up Earth's gravity from 9.8 to 10 so all you do is roughly find your weight on Earth. Next do the Moon and your weight there should be about six times lower than on earth. If you get these two figures correct you are doing it OK.
