Saturn Weight Formula
- W_saturn = Saturn-model gravitational force; the primary result is in newtons, with pound-force and Earth-calibrated kg scale equivalents
- W_earth = your weight on Earth
- g_saturn = 10.44 m/s² (fixed equatorial central-gravity approximation at 1 bar, excluding rotation)
- g_earth = 9.80665 m/s² (standard Earth gravity)
If you start from mass instead of weight, the calculator uses W_saturn = m × g_saturn. To go from a Saturn weight back to Earth, the ratio is flipped: W_earth = W_saturn × (9.80665 / 10.44).
Saturn has no solid surface. This calculator retains a fixed 10.44 m/s² approximation to GM/r² at the equatorial 1-bar radius, excluding rotation. Its Saturn/Earth ratio is about 1.0646. NASA separately lists mean gravity 11.19 m/s² and apparent equatorial/polar accelerations of 8.96/12.14 m/s²; a real scale reading depends on latitude and rotation.

| Earth weight (lb) | Saturn weight (lb) | Earth weight (kg) | Saturn kg scale equivalent |
|---|---|---|---|
| 50 | 53.2 | 25 | 26.6 |
| 100 | 106.4 | 50 | 53.2 |
| 150 | 159.7 | 70 | 74.5 |
| 200 | 212.9 | 90 | 95.8 |
| 250 | 266.1 | 110 | 117.1 |
Saturn’s gravity is unusually close to Earth’s despite the planet being about 95 times more massive. The reason is its low density and large radius.
| Body | Fixed comparison gravity (m/s²) | Weight ratio vs Earth |
|---|---|---|
| Earth | 9.81 | 1.000 |
| Saturn | 10.44 | 1.064 |
| Jupiter | 24.79 | 2.528 |
| Neptune | 11.15 | 1.137 |
| Uranus | 8.69 | 0.886 |
Example and FAQ
Example. You weigh 165 lb on Earth. On Saturn: 165 × (10.44 / 9.80665) = 165 × 1.0646 ≈ 175.7 lb.
Why isn’t Saturn’s gravity much higher? Saturn is enormous but mostly hydrogen and helium, with an average density less than that of water. Its 1-bar “surface” sits far from the planet’s center, which weakens the gravitational pull at that radius.
Does my mass change on Saturn? No. Mass stays the same. Only weight, the force gravity exerts on that mass, changes.
Why does the calculator show “kg scale equivalent”? An Earth-calibrated scale measures force and divides by standard Earth gravity. The displayed kg scale equivalent changes under the selected fixed gravity approximation even though mass stays unchanged; actual apparent Saturn readings depend on latitude and rotation.
