Weight on Jupiter Calculator

Convert a mass or Earth-scale weight into the equivalent reading or force on Jupiter. Jupiter gravity used: g_J = 24.79 m/s². Earth gravity: g_E = 9.807 m/s².

Formulas

Mass to weight on Jupiter: WJ (N) = m × gJ.
Earth-scale reading to Jupiter-scale reading: kgJ = kgE × (gJ / gE) where gJ/gE ≈ 2.528.

Note: Jupiter is a gas giant without a solid surface; this calculator gives theoretical gravity-equivalent values for education and comparison.

How the Calculator Works

A “Weight on Jupiter” calculator converts your Earth weight or mass into the equivalent force (or scale reading) you would experience on Jupiter. Because Jupiter’s surface gravity is stronger than Earth’s, objects feel heavier there. The calculator either (a) converts mass (kg) to Newtons (N) using local gravity, or (b) converts an Earth scale weight (what you normally read in kg on Earth) into the equivalent scale reading you’d see on Jupiter.

Quick note: scientists distinguish mass (kg, invariant) from weight (a force measured in Newtons). For everyday calculators we often report the “weight-equivalent” in kg — the number a bathroom scale would show if it used Earth calibration.

Core Formulas

1) If you have mass (kg):

• Weight (N) on Jupiter = mass (kg) × g_J
• Example: W_J = m × 24.79 (m/s²)

2) If you have Earth scale weight (kg reading):
First convert Earth kg reading to mass: m = W_Earth_kg (approx—since bathroom scales output mass assuming Earth gravity). Then:

• Equivalent scale reading on Jupiter (kg-equivalent) = W_Eq = W_Earth_kg × (g_J / g_E)
• Use g_E = 9.807 m/s² and g_J = 24.79 m/s².
• So W_Eq ≈ W_Earth_kg × 2.528

Example Calculation

If your Earth scale shows 70 kg:

• Equivalent on Jupiter ≈ 70 × (24.79 ÷ 9.807) ≈ 70 × 2.528 ≈ 177.0 kg
  So a 70-kg person would register about 177 kg on a Jupiter-calibrated scale (or experience a weight force of ≈ 70 × 24.79 ≈ 1,735 N).

Why This Matters

• Useful for education, science outreach, or curiosity.
• Helps compare gravitational effects across planets.
• Important in aerospace and mission planning (forces on structures and humans change with gravity).

Practical Notes & Caveats

• Jupiter is a gas giant with no solid “surface” like Earth; the gravity quoted is the effective gravity near the cloud tops.
• Atmospheric pressure, composition, and rotation make real surface conditions inhospitable; this calculator is purely theoretical.
• Use the mass-based formula for physics accuracy, or the scale-equivalent formula if you want the number a bathroom scale would show.
