Your mass is constant; your weight is local

Converts your weight to what a scale would read on the Moon, Mars, Jupiter and the rest of the solar system.

Mass is how much of you there is, and it does not change anywhere. Weight is the force the ground pushes back with, and it depends entirely on the gravity where you are standing.

So the same person reads 70 on a scale on Earth, about 12 on the Moon, 26 on Mars and 165 on Jupiter — if you could stand on Jupiter, which has no surface to stand on.

What to keep in mind

Surface gravity is taken relative to Earth's 9.81 m/s². For the gas giants it is the value at the cloud tops, since there is no surface.
Only gravity is considered. Nothing here says whether you could survive standing there, and mostly you could not.

FAQs

What is the difference between mass and weight?

Mass is measured in kilograms and never changes. Weight is a force, measured in newtons, and equals mass times the local gravity. Bathroom scales show weight but are labelled in kilograms, which is where the confusion comes from.

Why is the Moon a sixth of Earth?

It is both much smaller and less dense. Gravity depends on mass and on how close the surface is to the centre, and the Moon loses on both counts.

Why is Saturn's gravity almost Earth's?

Saturn is enormous but extremely light for its size — less dense than water. The huge mass and the huge radius nearly cancel out at the cloud tops.

Would I feel lighter on Mars?

Immediately. At 38 percent of Earth's gravity a step meant for Earth would launch you, which is exactly what the Apollo footage of the Moon shows.

Worked example

Seventy kilograms

Input: 70 kg measured on Earth

Output: 11.6 on the Moon, 26.4 on Mars

Note: Mars and Mercury come out almost identical — 0.377 against 0.378 of Earth's gravity — despite Mars being twice the mass, because Mercury is much denser and its surface much closer to its centre.
