Brinell hardness calculator

1. Brinell hardness is a method used to measure the hardness of materials, typically employed to test harder materials such as metals.

2. This tool calculates Brinell hardness based on the applied force, the diameter of the steel ball, and the indentation depth.

3. Calculation formula: BHN = (2×P)/[(π×D)(D−√(D²−d²)]

4. Note: In this tool’s calculations, pi (the mathematical constant) is set to 3.14.
