Find weight W = m g, the gravitational force on a mass.
| Weight (N) | – |
Use this calculator to convert mass to weight: mass in kilograms times g in m/s² is newtons.
On Earth g ≈ 9.81 so 70 kg weighs about 687 N. Mars is about 3.71 m/s², the Moon about 1.62 m/s². This is force, not mass; bathroom scales that say kg are inferring mass from Earth weight.
Mass (kg): Mass in kilograms.
g (m/s²): Local gravitational field. 9.81 on Earth.
Weight (N): W = m g, in newtons.
