We calculate weight by **multiplying mass by the gravity on the surface of the planet**. So, if you know your weight on Earth and the surface gravity on Earth, you can calculate your mass. You can then calculate your weight on any other planet by using the surface gravity of that planet in the same equation.

## How do you calculate your weight on other planets?

Calculate your weight on another planet by multiplying your weight times the relative surface gravity of the other world. For example, let’s calculate your weight on Neptune if you weigh 158 lbs on Earth. Gravity on Neptune is 1.19 time higher than on Earth.

## How do you calculate your weight on Neptune?

Being that it takes the weight of an object on earth and converts it to the weight on Neptune, the formula is Weight on Neptune= (Weight on Earth/9.81m/s2) * 11.15m/s2. To find the weight on Neptune, we divide the weight on earth by the earth’s force of gravity, which is 9.81m/s2.

## What is your mass on Earth?

On Earth, gravity accelerates at 9.8 meters per second squared (9.8 m/s^{2}). For example, to determine the mass of an object weighing 667 Newtons, calculate as follows: 667 Newtons ÷ 9.8 m/s^{2} = 68 kilograms. Convert the mass measured in kilograms to the mass in pounds. One kilogram is equal to 2.20462262 pounds.

## What is Kepler’s third law formula?

If the size of the orbit (a) is expressed in astronomical units (1 AU equals the average distance between the Earth and Sun) and the period (P) is measured in years, then Kepler’s Third Law says P2 = a3.

## What is the mass of Earth in KG?

Mass is always constant for a body. One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.

## What’s my weight on the moon?

Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds.

## What is my weight in mercury?

For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That’s because Mercury weighs less than Earth, and therefore its gravity would pull less on your body. If, on the other hand, you were on heavy Jupiter, you would weigh a whopping 253 pounds!

## Which planet would I weigh the most?

Jupiter is the largest planet in our Solar System with the most mass. Because of Jupiter’s mass, you would weigh more on that planet than on any other one in our Solar System. If you weighed 68 kg on Earth then you would weigh 160.7 kg on Jupiter, over twice your normal weight.

## Is your weight actually your mass?

We often use the words ‘mass’ and ‘weight’ interchangeably, but they mean quite different things. Your mass is the same no matter where you go in the universe; your weight, on the other hand, changes from place to place. Mass is a measure of how much force it will take to change that path.

## How do you convert kg to mass?

Fw = m * 9.8 m/s^2. Fw = 30 kg * 9.8 m/s^2 = 294 N. To change from weight to mass divide by gravity (9.8 m/s^2).

## Is KG a weight or a mass?

In the International System of Units (SI), the kilogram is the basic unit of mass, and the newton is the basic unit of force. The non-SI kilogram-force is also a unit of force typically used in the measure of weight.
