Jupiter Weight Formula
Weight depends on the chosen gravity reference. NASA’s Jupiter fact sheet lists mean gravity of 25.92 m/s² and equatorial acceleration of 23.12 m/s² at the 1-bar level, with Earth comparisons of 9.82 and 9.78. The calculator also retains a conventional 24.79 m/s² comparison, as published by ESA, paired with standard Earth gravity 9.80665. Mass stays constant.
- 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; these are stated atmospheric/gravity references, not a place where a person could stand. Gravity varies with position and reference convention. Force is expressed in N, kgf or lbf; mass is expressed separately in kg or lb and does not change between planets.
The calculator has three tasks: convert Earth weight force to Jupiter, calculate both weight forces from object mass, or reverse Jupiter weight force to Earth. The selected gravity ratio controls the calculation; the default is the commonly cited 24.79 / 9.80665 ≈ 2.527876, which the formulas, examples and first table below also use. NASA equatorial (23.12 / 9.78) and mean (25.92 / 9.82) references are available too.

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 × (24.79 / 9.80665) ≈ 176.9 kgf 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. Rotation, latitude, altitude and the definition of gravity matter. NASA’s current fact sheet distinguishes 23.12 m/s² equatorial acceleration from 25.92 m/s² mean gravity. The conventional 24.79 value is a separate comparison and should not be mislabeled as either current NASA value.
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.
