In the SI, it is DEFINED as a base unit, together with the unit of length, the unit of time, and a few others. Other units are derived from these base units.
The fundamental unit is the gram. However the standard unit (SI) used is the kilogram (1000 grams).AnswerThe terms 'fundamental unit' or 'standard unit' are not used in SI. The correct term is 'base unit', and the base unit for mass is the kilogram.

gravitational force is weakest force among the fundamental forces in nature per unit mass.

If you mean in the SI, it is defined to be a fundamental unit. Consider, for example, Newton's Second Law (force = mass x acceleration), used to define force as a derived unit in the SI. Acceleration is already a derived unit (derived from distance and time) - let's keep it this way, for the sake of discussion. Now, in SI units, force is defined to be derived from mass (and acceleration). Mass is the "fundamental" unit, and force is the "derived" unit. The same relationship, i.e. Newton's Second Law, could just as well have been used the other way round. That is, force could have been defined as the fundamental unit, and mass derived from force (and acceleration). The creators of SI basically defined certain units as "base units" because they could be defined with a high degree of precision.
A metric unit of measurement for mass is called a gram.
The fundamental units of heredity are called genes.
A kilogram is the base unit for mass in the SI system.
The mass per unit volume of a substance is called density.
