Principals

The hardness can be expressed by the pressure (N) a dynamometer applies over a specific unit area (S). The ratio of this force to the area is defined as the surface hardness (P).
P = N / S
P = Hardness value of item ( Kg/cm2 )
N = Pressure of dynamometer ( N, Kg, LB )
S = Area of pressure ( m2, cm2 )
