Your weight on Mars would be 28.5 kg. To find this result:
Measure your weight on Earth: W(Earth) = 75 kg.
Measure the acceleration due to gravity on Mars's surface: g(Mars) = 3.73 m/s² and Earth's surface g(Earth) = 9.81 m/s².
Multiply your weight on Earth by the ratio between g(Mars) and g(Earth):
W(Mars) = W(Earth) × g(Mars)/(g(Earth) = 75 × 3.73/9.81 = 28.5 kg.
This vast difference will make flying from Mars to Earth easy as pie! Read more
