How Is Vickers Hardness Test Calculated?

How Is Vickers Hardness Test Calculated? The Vickers number (HV) is calculated using the following formula: HV = 1.854(F/D2), with F being the applied load (measured in kilograms-force) and D2 the area of the indentation (measured in square millimetres). How is hardness value calculated? A hardness test is typically performed by pressing a specifically dimensioned
