Your weight depends on the local strength of gravity, so the same body weighs very different amounts across the solar system even though its mass never changes. This calculator takes your weight on Earth and multiplies it by the surface gravity ratio of each world to show what you would weigh on the Moon, Mars, Jupiter and the rest. On the Moon gravity is only about one sixth of Earth, so you would feel light, while on Jupiter you would weigh more than twice as much. The values use accepted surface gravity figures relative to Earth. It is a fun and genuinely educational way to build intuition about gravity for students, space fans and anyone curious about the planets.

It multiplies your Earth weight by the ratio of each planet's surface gravity to Earth's gravity.
Yes. The Moon's surface gravity is about one sixth of Earth's, so you would weigh roughly one sixth of your Earth weight.
No. Your mass stays the same everywhere. Only your weight changes because weight depends on local gravity.
