The formula for calculating Brinell Hardness Number Calculator is

HBW = 0.102*
2P / πD(D - √D2- d2)

The formula for calculating Surface area of indentation (A) is

A = 0.102*
2P / HBW

Example of Calculations:

Applied load (P): 3N

Diameter of indenter (D): 4 mm

Diameter of indentation (d): 2 mm

HBW = 0.102*
2*3 / π*4(4 - √42- 22)
= 0.09088 MPa (MegaPascals)

A = 0.102*
2*3 / 0.09088
= 6.734 mm2 (square millimeters)
