Planetary Weight and Age Calculator
What much do I weigh?
Your weight varies directly with your mass (your mass is how much matter is present in your body) and the mass of the planet you're
on. The more mass you have, the more you'll weigh. Also, the more mass the planet has, the more you'll weigh. So what do I weigh on
all the planets? Find out below.
How old am I?
Your age in years equals the number of times the Earth has revolved around the Sun while you've been alive. Translating the number of
Earth revolutions into revolutions on another planet and converting back to Earth-years gives your age on that planet. Try it out
below.
