Steel Hardness Conversion
Quickly convert between HB, HRC, HRB, and HV scales.
Hardness Conversion Calculator
How to use: Enter a value into any single field below (e.g., if you know the HRC, type it in the "Rockwell C" box) and click "Calculate". The tool will automatically find the equivalent values for the other scales.
Note: Conversions are approximate and based on standard steel hardness tables (ASTM E140). Results are based on the nearest available standard value.
Hardness Conversion Table
This table lists the approximate relationship between Brinell, Vickers, and Rockwell hardness scales, as well as the approximate Tensile Strength for steel.
| Vickers (HV) | Brinell (HB) | Rockwell C (HRC) | Rockwell B (HRB) | Tensile Strength (N/mm²) |
