Planetary Weight Formula:
| From: | To: |
The Planetary Weight Formula calculates your weight on different celestial bodies based on their gravitational acceleration compared to Earth's gravity. Weight is a measure of the gravitational force acting on a mass.
The calculator uses the planetary weight formula:
Where:
Explanation: The formula calculates how much you would weigh on another planet by scaling your Earth weight according to the ratio of the planet's gravity to Earth's gravity.
Details: Understanding how weight changes on different planets is important for space exploration, astrophysics education, and satisfying curiosity about how we would experience different gravitational environments.
Tips: Enter your Earth weight in kilograms, the gravity of the target planet in m/s², and Earth's gravity (default is 9.81 m/s²). All values must be positive numbers.
Q1: Why does weight change on different planets?
A: Weight is the force of gravity acting on your mass. Different planets have different gravitational accelerations, so your weight changes while your mass remains constant.
Q2: What are some examples of planetary gravities?
A: Moon: 1.62 m/s², Mars: 3.71 m/s², Jupiter: 24.79 m/s², Venus: 8.87 m/s².
Q3: Is mass the same as weight?
A: No, mass is the amount of matter in an object (constant everywhere), while weight is the force of gravity acting on that mass (varies with gravity).
Q4: Why is Earth's gravity 9.81 m/s²?
A: This is the average gravitational acceleration at Earth's surface, which varies slightly depending on location and altitude.
Q5: Can I calculate my weight on exoplanets?
A: Yes, if you know the gravitational acceleration of the exoplanet, you can use this formula to estimate your weight there.
