How is 1 gram defined?

Definition of gram (Entry 2 of 5) 1 : a metric unit of mass equal to ¹/₁₀₀₀ kilogram and nearly equal to the mass of one cubic centimeter of water at its maximum density — see Metric System Table. 2 : the weight of a gram under the acceleration of gravity.

Is GM and G the same?

The gram (abbreviation, g or gm) is the cgs (centimeter/gram/second) unit of mass. A force of one dyne (1 dyn), applied to a mass of one gram (1 g), will cause that mass to accelerate at one centimeter per second squared (1 cm/s2). … In the International System of Units (SI), the kilogram is the preferred unit of mass.
