Jupiter Weight Formula
Weight depends on the local gravitational acceleration. Earth’s surface gravity is 9.80665 m/s². Jupiter’s gravity at the cloud tops (the 1-bar pressure level) is about 24.79 m/s². Since mass stays constant, you scale weight by the ratio of the two gravities.
W_jupiter = W_earth * (g_jupiter / g_earth) = W_earth * 2.528
W_earth = W_jupiter * (g_earth / g_jupiter) = W_jupiter * 0.3956
- W_earth = your weight on Earth (lb, kg-force, or N)
- W_jupiter = equivalent weight on Jupiter in the same unit
- g_earth = 9.80665 m/s²
- g_jupiter = 24.79 m/s² at the 1-bar level
Jupiter has no solid surface, so “weight on Jupiter” means weight at the visible cloud tops. Deeper inside the planet gravity is stronger. The kg and lb readings here are weight expressed in those units (kg-force and pound-force), not mass. Mass does not change between planets.
The calculator has two modes. Earth to Jupiter multiplies your input by 2.528 to give Jupiter weight. Jupiter to Earth divides by 2.528 to recover the Earth equivalent. The unit selector (lb, kg, N) only changes how the value is displayed; the underlying math runs in newtons.

Worked Examples and FAQ
Example 1. You weigh 160 lb on Earth. On Jupiter:
160 × (24.79 / 9.80665) = 160 × 2.528 = 404.5 lb.
Example 2. A probe reads 500 N at Jupiter’s cloud tops. Earth equivalent:
500 × (9.80665 / 24.79) = 500 × 0.3956 = 197.8 N (about 44.5 lb).
Example 3. A 70 kg astronaut would feel 70 × 2.528 = 176.9 kg of force pressing them down on Jupiter. Their mass is still 70 kg.
Why is Jupiter’s gravity only about 2.5× Earth’s when it has 318 times the mass? Gravity at the surface depends on both mass and radius. Jupiter’s radius is about 11 times Earth’s, and gravity falls off with the square of distance from the center. The large radius cancels most of the mass advantage.
Could a person stand on Jupiter? No. Jupiter is mostly hydrogen and helium with no solid surface. The “weight” calculated here is what a scale would read at the 1-bar atmospheric pressure level, used as a reference altitude.
Does Jupiter’s gravity vary across the planet? Yes. Jupiter rotates fast and bulges at the equator, so equatorial gravity is slightly lower than polar gravity. The 24.79 m/s² value is the standard equatorial reference.
Why does the calculator accept newtons? Newtons are the SI unit of force, and weight is a force. If you have a reading from a force sensor or physics problem in newtons, you can enter it directly without converting to pounds or kilograms first.
