Weight on Other Planets Calculator

Weight is the gravitational force acting on a mass. Your mass is measured in kilograms (kg), while your weight as a force is measured in newtons (N). The same mass has a different weight where gravitational acceleration differs.

The calculator uses these fixed gravity values, in m/s²:

• Mercury: 3.7
• Venus: 8.87
• Earth: 9.81
• Moon: 1.62
• Mars: 3.71
• Jupiter: 24.79
• Saturn: 10.44
• Uranus: 8.69
• Neptune: 11.15
• Pluto: 0.62

These are the tool's calculation values, not measurements at every location. The giant planets have no solid surface to stand on, so their results are comparisons rather than a person's actual standing weight.

1. Enter a positive mass in kilograms (kg).
2. Select Calculate to see the estimated weight in newtons (N) for each body.

For example, a mass of 10 kg produces 98.10 N on Earth and 16.20 N on the Moon with this tool's values.

The calculator multiplies mass by gravitational acceleration:

Weight (N) = mass (kg) × gravity (m/s²)

Doubling the mass doubles the calculated weight. Local gravity can vary with altitude, latitude, and other conditions, which this simple comparison does not account for.

Compare how gravity changes the force acting on an object with the same mass. This is a simple way to explore the difference between mass and weight in physics lessons.

For engineering or mission planning, use location-specific gravity data and a model suited to the actual operating conditions.
