en.wikipedia.org/wiki/Hardness_comparisonThere are a large number of hardness testing methods available ( Vickers, Brinell, Rockwell, Meyer and Leeb).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.. Hardness comparison table
hapcoincorporated.com/resources/hardness-comparison-chartHardness may be defined as a material’s resistance to permanent indentation. The durometer scale was defined by Albert F. Shore, who developed a measurement device called a durometer in the 1920s. A chart showing general hardness comparisons is below. Some of HAPCO’s materials are available in both Shore A and Shore D.
matmatch.com/learn/process/hardness-comparisonHardness describes the resistance that a material exhibits to permanent indentation or marking by scratches. There are six main hardness tests that can be carried out. Which one to apply depends on the type of material to be tested and the equipment available.
