Weight on Other Planets Calculator

This your weight on other planets calculator helps calculate how much a person or object would weigh on other worlds i.e. Mercury, Venus, Mars, Saturn, Uranus, and Neptune.

• Mercury: 0.38
• Venus: 0.91
• Earth: 1.00
• Mars: 0.38
• Jupiter: 2.34
• Saturn: 1.06
• Uranus: 0.92
• Neptune: 1.19

While an object’s mass remains constant regardless of its location in the universe, its weight varies depending on the gravitational pull of the planet or moon it’s on. For instance, a person who weighs 100 pounds on Earth would weigh significantly less on the Moon due to its lower gravity.

Weight on Other Planets Formula

The formula to calculate weight on different planets is:

W = m * g

Where:

• W is the weight on the planet
• m is the mass of the object
• g is the acceleration due to gravity on the planet’s surface

In this formula, the gravitational force of Earth is approximately 9.81 m/s².

• Mercury: Weight on Mercury = Weight on Earth × (3.7 m/s² / 9.81 m/s²)
• Mars: Weight on Mars = Weight on Earth × (3.711 m/s² / 9.81 m/s²)
• Jupiter: Weight on Jupiter = Weight on Earth × (24.79 m/s² / 9.81 m/s²)

For instance, if someone weighs 200 pounds on Earth, their weight on Jupiter would be calculated as follows:

Weight on Jupiter = 200 lbs × (24.79 / 9.81) ≈ 505.6 lbs

To calculate the weight of a 100 kg object on Mars:

1. Earth weight = 100 kg * 9.8 m/s² = 980 N
2. Mars weight = 980 N * 0.38 = 372.4 N

How to Calculate Weight on Other Planets

• Determine the object’s mass in kilograms.
• Calculate the object’s weight on Earth using W = m * g (where g = 9.8 m/s²).
• Multiply the Earth weight by the relative gravity of the desired planet.

Weight of a 75 kg Person on Jupiter

Mass = 75 kg

Earth weight = 75 kg * 9.8 m/s² = 735 N

Jupiter’s relative gravity = 2.34

Weight on Jupiter = 735 N * 2.34 = 1,719.9 N

This person would weigh about 386.6 pounds on Jupiter!

What Would a 150 Pound Person Weigh on Mars?

Weight on Mars = 150 lbs × (3.711 / 9.81) ≈ 57 lbs

To solve this, we’ll use the following steps:

• Convert 150 pounds to kilograms: 150 lbs ÷ 2.2 = 68.18 kg
• Calculate Earth weight in Newtons: 68.18 kg * 9.8 m/s² = 668.16 N
• Multiply by Mars’ relative gravity: 668.16 N * 0.38 = 253.9 N
• Convert back to pounds: 253.9 N ÷ 9.8 m/s² * 2.2 = 57 lbs

A 150-pound person would weigh approximately 57 pounds on Mars.

How Much Would a 100 Pound Person Weigh on Neptune?

Weight on Neptune = 100 lbs × (11.15 / 9.81) ≈ 113.5 lbs

Convert 100 pounds to kilograms: 100 lbs ÷ 2.2 = 45.45 kg

Calculate Earth weight in Newtons: 45.45 kg * 9.8 m/s² = 445.41 N

Multiply by Neptune’s relative gravity: 445.41 N * 1.19 = 530.04 N

Convert back to pounds: 530.04 N ÷ 9.8 m/s² * 2.2 = 119 lbs

A 100-pound person would weigh about 119 pounds on Neptune.

How Much Would a 150 lb Person Weigh on Mercury?

Weight on Mercury = 150 lbs × (3.7 / 9.81) ≈ 56.6 lbs

Convert 150 pounds to kilograms: 150 lbs ÷ 2.2 = 68.18 kg

Calculate Earth weight in Newtons: 68.18 kg * 9.8 m/s² = 668.16 N

Multiply by Mercury’s relative gravity: 668.16 N * 0.38 = 253.9 N

Convert back to pounds: 253.9 N ÷ 9.8 m/s² * 2.2 = 57 lbs

A 150-pound person would weigh 57 pounds on Mercury, the same as on Mars due to their identical relative gravities.
