This equation computes the force of gravity due on input Grams in units of Newtons at the surface of the Earth. The Newton (symbol: N) is the International System of Units (SI) derived unit of force.
Note: The user should be aware that units of grams and units of Newtons are not equivalent and that this calculation is an approximation which is accurate at sea level on the planet Earth in the neighborhood of North America. It is a common usage error to think of pounds or kilograms as weight, but both are units of mass. Only when we apply force of gravity can we compute the weight of an object and that weight is only accurate for a specified acceleration factor applied at a relative distance from a mass (approximately 9.81 msec2 in this stated case). You'll note that this factor of gravity is non negligible in our assessment of weight since, due to the equatorial bulge and the effects of the Earth's inertia, sea-level gravitational acceleration increases from about 9.780 ms2 at the Equator to about 9.832 ms2 at the poles. so you really do experience a different weight due to gravity at different locations on the Earth.
