How it works

Your mass doesn't change: gravity does. Apparent weight = mass × (body's g / Earth's g). On the Moon, gravity is 16.5% of Earth's.

Results are for guidance only and do not replace professional advice.

Worked example

With the default values:

  • Your mass on Earth (kg)70

you get:

  • On the Moon11.6 kg (equivalent)
  • On Mercury26.4 kg (equivalent)
  • On Venus63.3 kg (equivalent)
  • On Mars26.5 kg (equivalent)

Frequently asked questions

What do I need to enter?

Just fill in: your mass on earth. The result updates as you type.

Can you give an example?

Your mass on Earth (kg): 70 → On the Moon: 11.6 kg (equivalent); On Mercury: 26.4 kg (equivalent).
