Astronomical relationship
Formula
w_body = m × g_body ; w_body/w_Earth = g_body / g_Earth= 26.558835076198
Note
This result is a simplified model: it applies the displayed textbook formula to the values you entered, assuming ideal spherical bodies, circular orbits, blackbody radiation and perfect optics, and ignoring atmospheric seeing, relativistic corrections beyond those stated, cosmological models and measurement uncertainty. Use published ephemerides and catalogue data for real observations.

How is my weight on another planet calculated?+
The calculator multiplies your mass by the surface gravity of the chosen planet instead of Earth's 9.81 m/s². Your mass stays the same everywhere in the universe; only the weight (a force) changes because gravity differs from body to body.
Why is my weight on the Moon so much lower than on Earth?+
The Moon's surface gravity is about 1.62 m/s², roughly one-sixth of Earth's, because it has far less mass packed into a smaller radius. Since weight is mass times local gravity, a 1/6 gravity ratio gives a 1/6 weight ratio.
Why is Jupiter's surface gravity used even though it has no solid surface?+
Astronomers define Jupiter's 'surface' gravity at the altitude where atmospheric pressure equals 1 bar, roughly Earth's sea-level pressure. It's a standard reference level used for comparison, not an actual ground you could stand on.
Does my weight change on a planet with the same gravity as Earth but a different size?+
No — surface gravity depends on both mass and radius (g = GM/r²), so two very different planets can share the same surface gravity value. If the gravity value is equal to Earth's, your calculated weight will be unchanged, regardless of the planet's size.
Is the weight shown my Earth weight or my true local weight?+
It's your true local weight, meaning the actual force you'd feel pressing on a scale while standing on that planet. It uses your Earth-measured mass as the fixed input and applies the destination planet's gravity to get the result.
