How do I calculate my weight on different planets?

For my science project I have to calculate how much I weigh on the different planets... Is there like a website I could go to or something that could help me do that? Any help at all please? Thanks!

Here's a website that will calculate it for you: http://www.exploratorium.edu/ronh/weight/
Here is exactly what you are looking for:

I used to have an excel spreadsheet that show the calculations and the other information. I don't have it anymore. Taught general physical science in which this is a part of it when you are differentiating between weight and mass.

Note that mass is that amount of matter you have within your body as to where weight is associated with the pull of gravity on that mass.

Some Astronomy books provide the comparison data between the gravity on Earth and the gravity on other planets. It will usually be found in the little block of basic data on a particular planet, and is shown as follows:

Gravity on earth = 1.0

Gravity on the Moon = 0.35 (for example) (# not correct)

So on the Moon, you would take your Earth weight and multiply it by the suggested 0.35 to get the relative weight you would have on the Moon.
Google, (weight on other planets) and you will come up with many different sties to look at.The Best one for your homework would be Online conversion-your weight on other planets.

It has a easy to use calculator for each planet.All you have to do is put your weight in the box required and your weight for all planets will be showed straight away.

The reason you weight differs on other planets is because of the gravity.The less the gravity the less you would weigh and the more gravity the more you would weigh.It all depends on the gravity.

Hope that helps your grade a bit.
And the equation is:

Weight in Newtons = GMm/R^2

Weight in pounds = 0.225 GMm/R^2

G = 6.673E-11 m^3 kg^-1 sec^-2

M = mass of planet in kilograms

m = your mass in kilograms

R = radius of planet in meters

You can figure out your mass by stepping on the scales and working the equation backwards.

m = your mass in kilograms

m = (weight in pounds) Re^2 / (0.225 GMe)

Me = Earth's mass

Re = Earth's radius

m = 0.4536 (weight in pounds)

Now all you need to do is look up the mass and radius of the planet you want to check your weight on. Let's take Mars.

M = 6.4185E+23 kilograms

R = 3.3962E+6 meters

Weight in pounds = 0.225 GMm/R^2

If your mass is 60 kilograms, you'd weigh 132.3 pounds on Earth, but only 50.1 pounds on Mars.
