Brinell Hardness Number Calculator

The brinell hardness number is a value assigned to the hardness of alloys and metals. This calculator finds the brinell hardness number using the following formula:
Brinell hardness number = (2*L) / [ (π*S)(S – √(S2-D2)) ]
where L is the load, S is the steel ball diameter, and D is the depression diameter.
To find the brinell hardness number, simply fill in the values below and then click the “Calculate” button.

Brinell hardness number = 0.42378
