Planet Weight Formula:
| From: | To: |
The Planet Weight Calculator Based On calculates your weight on other celestial bodies using the gravitational acceleration of that planet compared to Earth's gravity. Your mass remains constant, but your weight changes based on the gravitational pull.
The calculator uses the formula:
Where:
Explanation: Weight is the force exerted on a mass due to gravity, so it varies with gravitational acceleration while mass remains constant.
Details: Understanding how weight changes on different planets helps in space mission planning, scientific education, and satisfying curiosity about how our bodies would feel in different gravitational environments.
Tips: Enter your Earth weight in pounds, the gravitational acceleration of the target planet in m/s², and Earth's gravity (default is 9.8 m/s²). All values must be positive numbers.
Q1: Why does weight change but mass stays the same?
A: Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass. Different planets have different gravitational pulls.
Q2: What are some common planetary gravity values?
A: Moon: 1.6 m/s², Mars: 3.7 m/s², Jupiter: 24.8 m/s², Venus: 8.9 m/s².
Q3: Can I use kilograms instead of pounds?
A: Yes, but be consistent. If you input Earth weight in kg, the result will be in kg on the target planet.
Q4: Why is Earth's gravity set to 9.8 m/s² by default?
A: This is the standard average gravitational acceleration on Earth's surface, though it varies slightly by location.
Q5: Does this work for any celestial body?
A: Yes, as long as you know its gravitational acceleration, you can calculate your weight on any planet, moon, or star.
