Brinell hardness calculator

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

2. This tool calculates Brinell hardness based on pressure, steel ball diameter, and indentation depth.

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

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