Pressure=thrust /area
thrust=force
∴pressure=force\area
this is the relation between force and thrust

There are many different kinds of forces, which can either be a push or a pull. Thrust is a kind of force: it's a push, usually created through the use of engines. 
OR
The total force acting normal to a surface is called thrust. 
Thrust acting on unit area is called pressure.If F is the thrust and A the surface area, then pressure 
P=F/A. 

The unit of pressure is pascal. 
1Pa=1N/m^2
