How much would a person that is 170 weigh on the surface of the moon and on Saturn?
You don’t state if the person weighs 170 N or has a mass of 170 kg. However, I’ll assume the latter, because a grown person would weigh much more than 170 N on Earth. (Note that the previous answerer apparently made the opposite assumption.) All you need to do is multiply this mass by the acceleration due to gravity at the surface of both astronomical bodies. The surface gravity of the Moon is 1.622 m/s^2 and that of Saturn is 8.96 m/s^2. This will give you answers in kg-m/s^2, which is the same as N.
