How old will you be on Mars?

Answer 1

Your age does not depend on your location (unless you travel somewhere at near-lightspeed). If you were to find your age in Mars years (1 Mars year = 1 orbit of Mars around the sun) instead of Earth years, you would have to divide your Earth-year age by 1.8808.

Answer 2

Age is measured in Earth years, so it is not directly transferable to Mars. On Mars, a year is 687 Earth days long, so you would need to use a conversion factor to determine your age in Martian years.
