The kilogram (Kg) rather than the gram is considered the base unit of mass in the SI units because the gram is so small. The old French spelling gramme is sometimes used but gm is wrong.
Gravitational Force the force of attraction between the earth's mass (for example) and bodies near its surface, the further apart the less gravity. The gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.
Gravity (g) the unit for measuring acceleration. For example 1 g = 9.81 m/s² is the acceleration due to gravity at the surface of the Earth.
