What this tool does
Your mass is the same everywhere; what changes is the pull of gravity, so a scale calibrated on Earth would read 38 % of your weight on Mars and more than double on Jupiter. The gravity and orbital periods are those of NASA's planetary fact sheet; for the gas giants, which have no surface, gravity is given at the cloud level where the pressure is one bar. Ages use the time each world takes to go round the Sun — on Mercury you would have a birthday every 88 days, on Neptune once in 165 years.
Formula
scale reading = mass × g_planet ÷ g_Earth · age = Earth years × 365.2 ÷ orbital period (days)

Limitations
- The default values are typical reference figures, not measurements of your situation. Replace them with your own data whenever you have it.
- The calculation runs at full precision and only the display is rounded. If you copy an intermediate value and retype it, small differences can appear.
