In the SI, force is expressed in newtons.
The Newton is the SI derived unit for force.
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.
Newton, the unit of force, is defined based on Newton's Second Law (F=ma), as the force required to give a mass of one kilogram an acceleration of 1 meter/second2. Thus, it is derived from these other units.
No. A Newton is a unit of force, while pressure is force per unit area. The standard unit of pressure is a Pascal, which is also a derived SI unit.
If you mean the gravitatioal field - other options are possible - units of acceleration are used for that. The force of gravity, of course, is expressed in units of force.

The newton (symbol: N) is the SI derived unit of force, named after Isaac Newton in recognition of his work on classical mechanics.
Pressure = force / area.

No. A Newton is a unit of force, while pressure is force per unit area. The standard unit of pressure is a Pascal, which is also a derived SI unit.
Pressure is defined as the amount of force applied to a given amount of area. Therefore pressure is derived from force and distance. Force itself is derived from time, distance, and mass and area is derived from distance.

The SI unit of weight is the newton (N), which is a Derived Unit.
