Gravitational field strength (g) is the strength of the gravitational field at a point, measured as the force experienced by 1 kg of mass. It is measured in N/kg.

On Earth, g ≈ 10 N/kg near the surface.

Weight (W) = mass (m) × gravitational field strength (g)

g varies: Moon 1.6 N/kg, Mars 3.7 N/kg, etc.
