The Hardness Unit Converter application converts the hardness into 12 types of units. The units to be converted by this application are Vickers hardness HV, Brinell hardness HBS, HBW, Rockwell hardness HRA, HRB, HRC, HRD, Rockwell superficial hardness HR 15 N, HR 30 N, HR 45 N, Shore hardness HS, and tensile strength MPa. Simply input the hardness value and select the unit of hardness with the unit selection button, it will be converted into 12 types of units. This application refers to the approximate conversion table of ASTM E 140 Table 1 and JIS, and data not in the table is calculated by polynomial approximation. Values in the range not normally used are indicated by ().
