A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels.

Brinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, 9.80665 m/s 2, to convert it to megapascals. The Brinell hardness number can be correlated with the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined ...

For annealed materials the Meyer hardness increases continuously with load due to strain hardening. [2] Based on Meyer's law hardness values from this test can be converted into Brinell hardness values, and vice versa. [3] The Meyer hardness test was devised by Eugene Meyer of the Materials Testing Laboratory at the Imperial School of ...

Brinelling / ˈ b r ɪ n ə l ɪ ŋ / is the permanent indentation of a hard surface. It is named after the Brinell scale of hardness, in which a small ball is pushed against a hard surface at a preset level of force, and the depth and diameter of the mark indicates the Brinell hardness of the surface.
