Your weight on Enceladus
Your mass does not change when you travel. Your weight does, because weight is a force and it depends on the local gravitational field.

Show the working
- Your mass = 70
- How high you can jump on Earth = 0.5
- gm = 7.211e9 = 7 211 000 000
- radius = 2.521e5 = 252 100
- Surface gravity = 7 211 000 000 / 252 100^2 = 0.113 462
- Gravity relative to Earth = 0.113 462 / 9.80665 = 0.011 569 9
- Your weight as a force = 70 * 0.113 462 = 7.942 33
- Your weight there, in kilograms-force = 7.942 33 / 9.80665 = 0.809 892
- Your weight in pounds-force = 7.942 33 / 4.4482216152605 = 1.785 51
- How high that jump would take you = 0.113 462 > 0 ? 0.5 * 9.80665 / 0.113 462 : 0 = 43.2156
- Time for something to fall one metre = 0.113 462 > 0 ? sqrt(2 * 1 / 0.113 462) : 0 = 4.198 46
- Your weight on Earth for comparison = 70 * 9.80665 = 686.466
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- surface gravity g = GM / r^2
- weight = mass x g
- jump height scales inversely with gravity for the same take-off energy
The gravitational constant G is the least precisely known fundamental constant, so results here are reported as rounded rather than exact.
Kilograms-force is what a bathroom scale reads. It is a force, not a mass, which is why the number changes and your mass does not.
Where the numbers come from
- GM and mean radius from planetary ephemeris and spacecraft tracking solutions.
