Your weight on Venus

Your mass does not change when you travel. Your weight does, because weight is a force and it depends on the local gravitational field. Venus rotates backwards, which is why its rotation period is written as a negative number.

Your weight there, in kilograms-force
63.314
≈ Rounded Weight on Venus
Your weight as a force

Surface gravity
8.8700 m/s2
Gravity relative to Earth
0.904 49
How high that jump would take you
0.553
Time for something to fall one metre

Your weight on Earth for comparison

Show the working
  1. Your mass = 70
  2. How high you can jump on Earth = 0.5
  3. gm = 3.24859e14 = 324 859 000 000 000
  4. radius = 6.0518e6 = 6 051 800
  5. Surface gravity = 324 859 000 000 000 / 6 051 800^2 = 8.870 04
  6. Gravity relative to Earth = 8.870 04 / 9.80665 = 0.904 493
  7. Your weight as a force = 70 * 8.870 04 = 620.903
  8. Your weight there, in kilograms-force = 620.903 / 9.80665 = 63.3145
  9. Your weight in pounds-force = 620.903 / 4.4482216152605 = 139.585
  10. How high that jump would take you = 8.870 04 > 0 ? 0.5 * 9.80665 / 8.870 04 : 0 = 0.552 796
  11. Time for something to fall one metre = 8.870 04 > 0 ? sqrt(2 * 1 / 8.870 04) : 0 = 0.474 845
  12. 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.

    Venus rotates backwards, which is why its rotation period is written as a negative number.

    Where the numbers come from

    • GM and mean radius from planetary ephemeris and spacecraft tracking solutions.
