Have you ever wondered how much you would weigh on Mars, Jupiter, or even Pluto? While your mass remains the same no matter where you go in the universe, your weight changes depending on the gravitational pull of the planet you’re standing on. A Planet Weight Calculator makes it easy to determine your weight on different planets within seconds.
Planet Weight Calculator
What Is a Planet Weight Calculator?
A Planet Weight Calculator is an online tool that estimates how much a person would weigh on another planet based on their Earth weight and the selected planet's gravity factor.
The calculator uses known gravitational values for planets in our solar system and compares them to Earth's gravity. Once you enter your weight on Earth and select a planet, the calculator instantly displays:
- Selected planet
- Earth weight
- Weight on the chosen planet
- Gravity factor relative to Earth
This allows users to quickly compare how gravity differs from one planet to another.
Understanding Weight vs. Mass
Before using the calculator, it's important to understand the difference between weight and mass.
Mass
Mass is the amount of matter contained in an object.
- Remains constant everywhere
- Measured in kilograms (kg)
- Does not change when moving between planets
For example, if your mass is 70 kg on Earth, it will still be 70 kg on Mars, Jupiter, or the Moon.
Weight
Weight is the force exerted on an object due to gravity.
- Changes depending on gravitational strength
- Measured in kilograms (commonly used for body weight) or Newtons
- Varies from planet to planet
This calculator focuses on how gravity affects your weight.
Why Does Weight Change on Different Planets?
Every planet has a different gravitational pull because of differences in:
- Mass
- Size
- Density
- Internal structure
Large planets with enormous mass generally exert stronger gravitational forces.
For example:
- Jupiter has much stronger gravity than Earth.
- Mars has weaker gravity than Earth.
- Pluto has extremely weak gravity.
As a result, your weight changes significantly when moving from one celestial body to another.
How to Use the Planet Weight Calculator
Using the calculator is simple and requires only a few steps.
Step 1: Enter Your Earth Weight

- Neptune
- Pluto
Step 3: Click Calculate
The calculator instantly computes your estimated weight based on the selected planet's gravity factor.
Step 4: Review Results
You'll see:
- Planet name
- Earth weight
- New weight on that planet
- Gravity factor
Step 5: Compare Different Planets
Try selecting multiple planets to see how your weight changes throughout the solar system.
Planet Weight Formula
The calculator uses a straightforward formula based on relative gravity.
Planet Weight=Earth Weight×Gravity Factor
Where:
- Planet Weight = Estimated weight on selected planet
- Earth Weight = Your current Earth weight
- Gravity Factor = Relative gravity compared to Earth
Planet Gravity Factors Used in the Calculator
The calculator includes the following planetary gravity multipliers:
| Planet | Gravity Factor |
|---|---|
| Mercury | 0.38 |
| Venus | 0.91 |
| Earth | 1.00 |
| Mars | 0.38 |
| Jupiter | 2.34 |
| Saturn | 1.06 |
| Uranus | 0.92 |
| Neptune | 1.19 |
| Pluto | 0.06 |
These values represent each planet's surface gravity relative to Earth.
Example Calculation
Let's see how the formula works.
Example
Suppose your Earth weight is:
80 kg
You want to know your weight on Jupiter.
Step 1
Earth Weight = 80 kg
Step 2
Jupiter Gravity Factor = 2.34
Step 3
Calculation:
Planet Weight = 80 × 2.34
Planet Weight = 187.2 kg
Result
| Measurement | Value |
|---|---|
| Earth Weight | 80 kg |
| Planet | Jupiter |
| Gravity Factor | 2.34 |
| Weight on Jupiter | 187.2 kg |
You would weigh approximately 187.2 kg on Jupiter.
Weight Comparison Across All Planets
Let's assume a person weighs 70 kg on Earth.
| Planet | Weight |
|---|---|
| Mercury | 26.6 kg |
| Venus | 63.7 kg |
| Earth | 70 kg |
| Mars | 26.6 kg |
| Jupiter | 163.8 kg |
| Saturn | 74.2 kg |
| Uranus | 64.4 kg |
| Neptune | 83.3 kg |
| Pluto | 4.2 kg |
This comparison clearly shows how dramatically gravity affects weight.
Why Jupiter Makes You Heavier
Jupiter is the largest planet in the solar system.
Its enormous mass creates powerful gravitational forces, making objects weigh significantly more than they do on Earth.
A person weighing 75 kg on Earth would weigh approximately 175.5 kg on Jupiter.
This doesn't mean their body gains mass—it simply experiences stronger gravitational pull.
Why Pluto Makes You Lighter
Pluto's gravity is extremely weak compared to Earth.
With a gravity factor of only 0.06, your weight becomes dramatically lower.
Someone weighing 100 kg on Earth would weigh only about 6 kg on Pluto.
This is why astronauts could jump much higher on low-gravity worlds.
Educational Benefits of a Planet Weight Calculator

Common Misconceptions About Planetary Weight
Myth 1: Your Mass Changes on Other Planets
False.
Mass remains exactly the same.
Myth 2: Heavier Planets Always Have Stronger Gravity
Not necessarily.
A planet's radius also affects surface gravity.
