There are a large number of hardness testing methods available (e.g. 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 e.g. for steels.
Hardness comparison table
Brinell HB (10 mm Ball, 3000 kg load) |
Vickers HV (1 kg) |
Rockwell C HRC (120 degree cone 150 kg) |
Rockwell B HRB (1/16" ball 100 kg) |
Leeb HLD[1] |
