Surely you have seen the images of the astronauts of the Apollo missions in the 1960s and 70s where they are “hopping” on the surface of the Moon. This is because due to the lower mass of the Moon, the force of gravity is also lower. As a result, a person would weigh approximately six times less than on Earth, making “hopping” a more efficient and easier way to move around than walking regularly.

This is good news because in order to be able to survive on the Lunar surface, you would have to use a very heavy spacesuit. An astronaut’s gear on a Moonwalk includes an oxygen tank, liquid cooling system, ventilation, vitals, and a battery backpack to power it all up.

To give you an idea of how much weight that is, the spacesuits that the Apollo astronauts used to walk on the Moon weighed about 163 kilograms (360 pounds) on Earth. Thankfully, on the Moon that weight was only about 27 kilograms (60 pounds) which is still a lot so you will still need to be in good shape to wear it.

So, how much would you weigh on the Moon?

Your weight on the Moon would be approximately one-sixth of your current weight on Earth. That means that a 70kg (154 lbs) person would weigh 11.5 kg (25 lbs) on the Moon. It can be precisely calculated using a simple rule of three that factors in the difference between the force of gravity on both planets.

The following calculator simplifies the process.

Weight on The Moon formula

The formula to calculate your weight on the Moon is as follows:

WMoon = (WEarth / 9.81) * 1.62

WMoon: Weight on the Moon

WEarth: Weight on Earth

The other two numbers are the force of gravity on each planet and it is given in meters per square second (m/s2). The force of gravity on Earth is 9.81 m/s2 and on the Moon, it is approximately 1.62 m/s2 or about one-sixth.
