How it was calculated
- W = m × g = 70 kg × 9.8067 m/s² = 686.4655 N

How the weight calculator works
Weight is the force of gravity on a mass: W = m × g. On Earth, standard gravity is 9.80665 m/s², so a 70 kg person weighs about 686 newtons (154 pounds-force).
A bathroom scale shows weight converted back to mass assuming Earth gravity, which is why you would 'weigh' about 16.5% as much on the Moon.
